Awesome!!! I love the Slant 6 the best engine ever!!!
PowerNation you guys should build a true ford 400 "big block"
+79tazman The 2JZ is the best Inline 6 engine. LSx is the best V8 engine in the world.
@@basshead. STFU 2 different engines with 2 different purposes.
+Cindy Sue They both are petrol Inline 6 engines.
The engine from the junkyard was perfect, you just had to replace the block and all the internals.
What was your premix ratio? you cannot ru these without oil injected into the intake, Duh
@John Christensen New handle and head, so how is that original?
Clive Bindley that’s the joke buddy
@@linemanlovesyou859 How is it a joke? If the handle and head have been replaced then it's not original. Some people are just dumb.
Just premix and run xd-100 that what i would do, the 225 is some type of valved fucked up 2 stroke anyways
Should be called "How to tear down a Slant six, throw it away and build a new one from scratch."
I'm cracking out , god I thought the same
You summed that up very well.
I had 4 of them and they were not a good engine . 100000 miles and they were junk . Newer engines are tremendously better .
Charles Wesley also putting the carb over the Iraq exhaust manifold doesn’t seem right
@@sleeplessvirus The metal used in them wouldnt make good slag .
1. Disassemble engine 2. Throw out the disassembled engine 3. Buy a new engine (not assembled) 4. Assemble new engine 5. “We rebuilt an engine”
I was about to comment the same thing. They didnt restore the original engine
Yes many different oil pans, I put another 225 in a duster with the 198 and turning took a whole parking lot until I got a better match.
old engine was good shop just didnt want to do work iv rebuilt them with 3 times the rust
Dropping contributors names the whole time. * every other new part mention. They bought this as junk, got what they bought. Shoulda started with a runner. This channel is the best, if you are working w an unlimited budget. - I could do this. …… With contributions from; Duplicolor, Summit, Comp Cams, Royal Purple, Sealed Power, Loctite, Felpro, King, Pioneer, ARP, Melling, Hooker, Edelbrock, …..,. And their “magic”.
I hate that they do this on all of these shows. Love how they try to make this relatable to the guy in his own garage but do everything the exact opposite of what the guy in the garage can do.
If anyone wants some more knowledge on the Chrysler Slant 6, just look up Uncle Tony’s Garage, that man seems to know everything about it
Best channel ever!
if you want to see what these engines are capable of, look at aussie engine builders. american engine builders are far too tame in comparison and never ever get adventurous.
3 e⁴3 we w5 see AR GA zee@@theghost6412
We bought this engine for $150 threw it away, then spent $3000 building a new one and called it the old one.
10 4
Lmao! Shiit
So true Mr.Kaye, so true.
You're not supposed to say that -- but yeah.
@@markmergatroid2348 Yep. And I bet that chrome valve cover adds 50hp!
I resurrected my old run down Honda civic by just buying a new one. Complete car revival.
Lol i seen you on other vids
Scott Wales yeah man, working on my comments. Just want to give people a good laugh.
😒😒
Wow, why don't u become a mechanic? Just telling people to buy a new one.
Alex.B Choi He/She was making a joke. The joke is about how the video replaced every part from the original engine. (100% sure about the explanation feel free to correct me.)
One of the finest engines ever produced.
Lmfao, not really.
Had a 4 door 67 dodge dart w/225 all through high school. The thing was a slow iron tank. Survived the blizzard of "78" with that thing and snow tires. I put the fold down "rambler" seats in it and made it into the "love machine"
title should be called, rebuilding an old engine by using none of the old parts
I think they reused the head. ;-)
Yeah, but it's still satisfying.
Yes we all had dynos,unlimited snap on&matco tools,parts washers,dial indicators...brand new everything,My parts washer when I started?, Yes a Buick hubcap,with gas...
and spending a shit ton of money
And how to cram as many product placements and ads in a single video as possible.
I had a 1964 Plymouth Valiant with the 225 engine. We had some horribly cold winters in Wisconsin back in the 70's. It was -10F for the high during the day for about two weeks. We started work at 6am so the cars were in the parking lot when the sun was barely up. It was probably -20 until about 10am. I think it was in January. After work, My little slant six always fired right up. After a couple minutes to warm up I would drive around the parking lot to see how many cars did not start. Some days there were a lot of them, all newer than my Valiant too. But those were the days of carburetors on big bore V-8's so they were at a disadvantage. I bought a huge battery for the Valiant from a farm implement dealer. It was a beast. So the guys got used to seeing the Valiant coming and they knew they were going to get a start. She made quite a reputation for reliability that year. It was a neat car as Valiants go. It was two door hardtop with bucket seats and four speed trans. The first and second gears were fairly low so it was actually pretty quick up to about 45 mph. I had made marks on the distributor so I could advance the timing by eye when I was able to get high octane fuel for it. 103 really did make a difference IF I advanced the timing. With a heavy duty clutch from the pickup line it would squawk the tires even in third gear with a power shift. It embarrassed some so called hot cars at the stop lights when they underestimated the little Valiant. It had a two barrel carb from the 273 engine and a 355 rear axle,
Ironic that later Valiants from around 1976 were horrible in wet and winter weather because of notoriously bad electricals.
I had a 64 Polara with the big block 318 , I live in the U.P. of Michigan on lake superior , back in 1970-71 we had a cold snap of -35 for three days , my car was one of the few in the parking lot that would start up good , worst starters we GM's with V8's , those gear reduction starters on mopars may have sounded funny but they worked !
I read and enjoyed your little story. The good ol days cold winters and carbs
@@sparkywirenut That's great! I suspect it had something to do with the intake manifold on that engine. I remember those well. I had one in a 57 Plymouth and they used them the first part of 1965 in the Plymouth Fury and Dodge Polara at the Belvidere plant where I worked shortly after graduating high school. For only 318 cubes that engine looked BIG. They went to the small block 318 to make more room under the hood. Chrysler wanted a V-8 to fit in the Valiant and Dart.
I FOUND out the autolite 2 barrel carb from fomoco where the best carb for the slant six.
The engineer of this engine was a genius
My dad owned a parts store I grew up in and we had a Black man named Mr Reynolds that had a 225. I'll never forget he came in and asked " Give me a breaker box and a rooster head for a duce and a quarter". He wanted a distributor cap and a rotor button for a 225!
I agree with the comments below, this is about building an engine not re-building an engine. Another amazing item is how all the valves fit miraculously without any lapping to insure a good seal. I guess that was another unimportant procedure not worth showing.
This wasnt much of an engine either, they only slapped it together roughly, by the end of it the engine was a lemon. They didnt even get it to be as powerful as a stock standard engines horsepower. It had far less than a stock standard engine. I was hoping for 160 to 180 horsepower atleast for all the work they supposedly did.
My brother had an old Barracuda that cam with a slant 6 and 4 speed trans. His build was similar to this except he put a little T3 turbo on it. Man, what a torque monster it turned out to be. Fun Ride.
I grew up around those old motors and IMHO they are the best inline 6 cylinders ever built period, they need to bring them back
The pride of Huber Ave. foundry! Iron block and head same birth place.
It is such a good feeling having that clean oil all over your hands when putting together a fresh engine. I miss having the money to grab a cool old motor just to tear it down and rebuild.
Slant Sixes are definitely indestructible! I drove my 1963 Valiant with a 198ci slant six for at least a year and a half with cracked block. You could even see the water seeping out the crack just below the exhaust manifold. Once the engine warmed up the crack would close up. I would always carry a couple extra gallons of water in car for that reason. After starting the engine I would fill the radiator up with water. I drove that to work everyday and wherever else I had to go. The engine never over heated. I love the car because it also has a manual transmission, "3 on the tree". The rear end was lot louder the engine is. Slant Six "THE LITTLE ENGINE THAT COULD !
"Ressurecting" Yes, like how I resurrect my kid's pet by buying him a new one
They made a slant six boat as well, they're so so so versatile
The slant 6 in my books is the toughest engine ever produced. I have a 74 Dart that I ran for years, one summer I blew a seal and ran it dry of oil 4 times before I fixed it. Each time the engine seized up, I would just add oil, take a wrench and turn the engine over. Then start it up with no issues. She ran for 6 more years after that with no issues till I sold her. Ran into the owner an about 5 years later around 93, and he told me it was still running.
I could say the same thing about the Briggs and Stratton that cuts my grass. I think I get stuck behind you every time I try to drive somewhere in a hurry.
@@taterlysaladman9377 you really don't know anything about what is being talked about here do you?
I'm not a Mopar guy but its damn hard to argue against the ol' Slant 6.
Slant 6 is the best it will outrun anything Uncle Tony has a 170 has a 170 with over a million miles has been running since 1964 and never played with and if you don't know who Uncle Tony is just look up Uncle Tony's Garage here on KZhead
@@LordHumungusFL won't outlast a slant six
In 1982 at Indianapolis Raceway Park, I saw a guy with race built slant 6 in a rail car run mid 8's at 156 mph.
@@LordHumungusFL The 300 was an awesome engine and made alot of torque for a straight six, they're both good engines in my opinion, and both very smooth running.
@@LordHumungusFL 300s were fuel hogs from hell. just get a 302.
Slant 6 ..one of the very best ever made. I miss those days ..
U guys are actually adding value to things and doing that in style. Keep up the good work.👍🏽
What a great engine. Those engines always got reused if the vehicle wore out or got totaled. Extremely reliable - easy to maintain - easy to fix. Like everything else today - we have gone backwards.
Yup. Crap now is built to fail so you will buy new crap that is meant to fail.
"Theres no need for high dollar fasteners to retain the cylinder head" Meanwhile uses ARP hardware for the oil pan and timing cover bolts...
Canuckrz thought that same thing. Head gaskets/ studs aren’t something you want to cheap out on
@@Ahnenerbe1944 To be fair, if they're not torque to yield bolts and its a fairly low stress engine its fine to reuse them assuming they haven't been corroded from sitting. I just thought that line was a bit rich considering all the things they made sure to name drop using expensive ARP hardware for.
I don't know why they used ARP parts in some places but not others. Since this build isn't extreme, and the head gasket isn't failure prone, it might not benefit from ARP fasteners. Engines with inadequate fasteners from the factory, such as the Ford 6.0 PSD are an example where you absolutely want to ARP studs. Also, sometimes when you add forced induction to an NA engine, or you dramatically increase boost in a factory forced induction engine, ARP studs are worth it.
Canuckrz It’s advertising for ARP
"A clean deck surface on the block and heads promotes a good valve seal between them and the head gasket." What does the head gasket have to do with the valves? lol, it would appear that "Power Nation" could use a knowledgeable editor/staff.
In 1982, got my DL in a '67 Dart with a 273 slant 6. That thing was bizarrely fast.
i had a slant 6 from the late 70s. Dodge had decided to make the distributor gear out of nylon. They saved 5 cents on production and I ended up with nylon pieces floating around in my cam gear. Thanks Dodge!
Just imagine. No computer modules to reset or sensors monitoring anything and everything. Easy access to plugs, wires, engine accessories, oil filter. A mere mortal can perform nearly all their own maintenance on the engine. Dare I say I miss those "good old days'?
Amen brother!!!
If cars didn't have to pass smog tests, there might not have been such a pressing need to replace the slant 6.
It would have been great to let Mexifornia have the newer trash engines with their computer headaches and let the rest of the country keep running the sleepy sixes.
Its tempting but dont be a Luddite. Remember 12 mpg and carbon monoxide headaches? Tuneups of spark plugs, wires, cap and rotor button [check points and dwell] with valve adjustments (and new cover gasket) every couple years? Yeah, The old days sound great. Even new shitboxes go 120k without any of this. And usually with no oil/coolant leaks .Stand in line for gas much??
That massive forged crank had a crack? Damn, must have had a million miles on it.
Captain 345 Probably froze and cracked from sitting
They didn’t use x-ray & sonic testing on forged and casted parts then. QC is far better today than back then. That’s not to take anything away from the Slant 6. It was an extremely durable design for that time period.Way back in my high school days, me and my best friend did our best to tear one up . We kept oil & water in it but absolutely thrashed it. We failed to kill it.
@@prevost8686 'Extremely' durable it is not. Average durable it is. I know. I fixed the effing things for years and they are about equal to any other inline 6 made by the big 3 of the era. They don't like being thrashed. They die. no.6 big end lets go and ventilates the block and smashes the starter off. I have seen at least a dozen do that. The big end bearing rotates, the oil hole blocks off, the big end gets hot, the rod bolt fails and bang bang bang grrr, grrr cough grrr clank clank clang - tissss, shhhhhhhhh .......... ......... ........
Captain 345 I think the machine shop wanted the block and crank probably told them that if they gave them the block and crank they wouldn't be charged for work
@@daveycrocket6277 Something similar happened with me I sent my block and head to another shop for CNC port work they told me block/head was clean after doing a magnaflux testing that other shop was trying to scam me
The Beauty of an in-line six engine is its longevity and reliability. My first vehicle was a 1969 dodge D 100 stepside. It was easy to work on. Parts were cheap.
Love this engine! My dad's '72 Dodge Charger had one, as well as my stepmom's '73 Dodge Dart Sport, and the '76 Dodge Dart sedan they both owned. Good engine.
1 of the best all time in line 6s ever made
Agreed. It's ashamed that had get rid of an engine that was dependable and reliable.
@@danielrowe2174 i had 1 YEARS AND YEARS ago,,,,LOL,, had way over 200000 miles in a 66 dodge dart wagon and was never torn apart excpet for maintenance,,,, sure it leaked some oil but wasnt bad,,,, sounded like a singer sewing machine but it was very dependable and still had all kinds of power for what it was,,,, it NEVER ailed me or left me stranded,,,,, all i did was oil changes and tune ups,,,,your 100% right,, the body gave up and was almost all bondo but the engine and trans was strong,,, that car didnt even have power steeering,,,, i was plling into my drive 1 day in the mid 70s and a van hit me in the rear,, pushed the back bumper to the rear diff,,,,,, it was a blast to drive,, i miss that car
The 198 was all forged and had an over square design. It was superior.The 225 does not rev being undersquare. This engine weighs a ton and so does the crank. Getting at the distributor was always a real pain. TO remove rusted in pistons pour Vinegar in the cylinders and wait a few days. Then just a few smacks and out they come. Your method is Brutal.
Getting at the distributor was a pain? Was easy as heck for me on my dart
225 was the least of the 3 as you said.
After working on my own cars, all 92 and newer and mostly imports, its fun to watch these videos of "old school" engines because everything seems just so simple and easy to work on. I need to get a classic car of some kind to mess with one day.
Build a short bed with a slightly modified slant 6. Small tranny, small driveshaft, small rear end makes for a quick little truck
"Leaning tower of power " I love it.
Thank God... something other than small block chevy or ford.... thank you!
My old man had a 1980 D-150 with this engine. IIRC, he put like 250k on the clock (which at the time was so unheard-of the local paper interviewed him about it) before he sold it.
I love seeing six cylinder engines getting hopped up. I love it when they are given EFI and best yet a TURBO!!!
"we replaced it" welp that's one way to resurrect it lmao. "It's like brand new!"
Those slant 6 engines are are like country music , they are here to stay . I had a 72 Plymouth with 300k and never did anything but oil/filter change and 1 rebuild of the 1 bbl carb , A semi ran over it and that was the end of her
Yet here you are, aren't we lucky?
Sometimes when you send the block or crank out to the machine shop they come back and say sorry it’s no good. Thank you for not lying about it and pretending it came back just fine. Actually there’s quite a bit more that can be done to this engine and they run surprisingly well.
When i worked for the U S Forest Service we had many Pick ups with The slant 6 engine. We NEVER had a problem wirh any of them.
I used to make these at Chrylser Trenton engine plant. One reason why it was such a good engine was that it could only be made one way and it was hard to mess it up
That makes no sense.
I worked at Trenton engine myself, as an electrician, from 91 through 05. I haven't worked with a more knowledgeable supervisor, Stan Marchewka, or smarter coworkers since. Great place to learn, very hands on place.
The slant six was one of the best engines Mopar ever made.
But why than that plastic distributor shaft gear.?
SO MUCH FOR YOUR TRUST BEARING WHEN YOU HAMMER IT IN
'64 Dart GT bought an aluminum intake off one of the mechanics that I worked with, put the 4 barrel on it and for a slant 6 it was awesome. Now I just drive the '13 Dart Limited, 1.4 turbo, leather interior, heated seats and steering wheel. My how time changes things.
Should be called "Buying a perfectly fine 225 Dodge Slant Six"
Buying a junked 225 Dodge Slant Six - then buying a perfectly fine one in parts...
Never seen one go bad ….that's why they found this one at the junkyard. The guy had it for sale for 40 years !
nothing left from the old engine... how is this resurrecting?
I was just thinking the same thing
Well... This is how we rebuild engines.
@@user-mj7gm6gj9v If nothing original is left over then it's not even the same engine anymore, you can't call that "ressurecting"... That's called REPLACING. Sit.
@@marceloho1984 Also not "rebuilding" if nothing original remains, called REPLACING.
This is my grandfather's axe. It's had its handle replaced three times, and its head replaced twice...
I am _really_ enjoying all these straight six builds.
In the 70's, I had several friends that built and raced the slant six.Surprised that the same race parts available. I was into the 426 Hemi.
I have a slant six in my 68 Ramcharger with a 4 speed manual. Great combo for off road.
Enjoyed the video, found this funny; ARP fasteners on timing cover and oil pan, later "no need for high dollar fasteners" for the head...
So happy somebody else found this funny
best engine ever created!! i owned a few slant 6 darts back in the early 90s, man,, i miss them!
Beautiful work and description of each step in the build. Thank You
I was under the impression the engine was going to get refurbished, not completely replaced with all new parts.
@Dave Micolichek yes, but you also at least try and reuse most of the old parts. Not just completely get rid of everything internal and external and only use the engine block, in that case just Buy a brand NEW Engine. NOT everyone has the money to just straight up replace everything in an engine... we are not all made of MONEY...
I've disassembled many " high value " core engines that were severely rusted up & never used an air hammer to force the pistons out . & I had most of them spinning over within an hour once down to the short block . But then , I'm not an idiot !
guess they never heard of rust penetrant :D
I'm so happy to see my favorite Mopar engine is getting long deserve recognition, it's not a hemi engine but I 💕 it anyway.
ONE THE BEST ENGINE DODGE EVER BUILT FOR THE AVERAGE CONSUMER
I'd call it the leaning tower of fuel efficiency
Leaning tower of easy driving
I always get bummed out when the engine they start the rebuild with isn’t the one they finish with.
Well, that happens in the real world. Junkyard engines are always a gamble.
@@chuckschillingvideos it depends on where they're from sometimes and how old they are, for example, if I'm looking for a Toyota 1uz-fe V8 engine (I don't care if people hate it since it's a Toyota) for a project car i can get one out of a car that looks mint but it could be in worse condition than one from a wrecked car (unless the car was wrecked head on there's always a chance it could be salvaged) because sometimes cars end up in the junkyard because the previous owner want a quick buck or for some reason the car just wouldn't run and they gave up on it, you will never know until you take it apart and rebuild it and look it over as you rebuild it while replacing parts here and there along the way just to be safe (like rings, sleeves, gaskets, etc.) And see if the block is still worth investing in once you get everything out
It’s like one of those “first starred in years“ videos where they just take the entire car and rebuild it from the frame up with a brand new engine.
chuckschilling yes, but what they did was buy a junkyard engine, tear it down, then throw the entire thing away and buy a bunch of new parts. They could’ve completely left off the first part of the video. The only thing that would have made it worse is if they just decided to build a V-8 instead
I'm just grateful that you can still do this in this day and time.
Had one in my 1964 dodge dart with push button transmission. Great times in that ol thing.
Love the upgrades you did on that legend of an engine.
Nice Video! I have a 1980 Dodge D-150 truck with the orig, 225 slant six with stick shift with about 90,000 orig. miles - my dad bought new for about $6500. Starts right up and runs great.
I had the 225 in my 74 Scamp, 75 Duster and 80 Le Baron. Greatest engine ever created!
What a nice, smooth and reliable engine. Love that olds slant six.
This is super cool! You all should do a Ford 300 straight 6.
They did. A little over 200 HP and 300 Ft Lbs of torque. it sounds pretty mean.
For those of you wondering "why did they lean it to one side?" It was designed to be a replacement for the old flat head six cylinder industrial engine. The only way they could get the much taller OHV engine to fit in the same engine compartments was to lay it over on its side. (They didnt want their industrial and commercial equipment customers to have to do major redesigns to fit in a modern engine) The off set water pump is so the fan would be in the same location. The only design change industrial equipment manufacturers had to do was deal with the exhaust flange being on the other side of the engine....other than that, they pretty much dropped into whatever the flat head six had been in. So the rumors of "they were going to make a V-12" ,"They wanted lower hood lines on their cars" and "Laying on its side compensated for torque wearing out the cylinders unevenly" is just urban legends. The indistrial engine had good overall performance so they started putting them into cars.
@Dave Micolichek No , the engine first appeared in the mid 50's as an industrial engine to replace the IM-6 flat head in Yale Forklifts ,they didnt even put it in automobiles originally. That this engine was in Yale forklifts a good five years before the first car had one , kind of blows your claim about hood lines right out of the water.
@Dave Micolichek You're trying to bullshit a forklift mechanic about when slant sixes first showed up in Yale forklifts. I'm not going to argue with you about it.
I had a 1975 Plymouth Duster. It had a 225 slant 6 in it with a “3 on the tree” transmission. On a cross-country trip we actually got 41 mpg!!!! Great engine, great car!!!
Call mythbusters!
The "Super Six" was THE "Kick-Ass" small motor! I have driven MANY cars (stock) in my days, but have NEVER RESPECTED "stock" 6 cylinder power SO MUCH! This was THE (cheap) KICK-ASS "6 cylinder"! A GROUND RIPPER!
The 225 was a solid, dependable engine. I had one in a Valiant.
Never Die!
Another trait, uncomplicated.
This makes me want to rebuild my aluminum block that i have collecting dust in the garage
What for? if it's in good condition sell it if it isn't going into a numbers matching resto. I know a guy that rebuilt an aluminum block 225 and he was thoroughly unamazed at the power for the money spent. The design doesn't lead itself to really good power increases because of a few things. The capacity is a bit small even at 225 for the stroke length, the small bore inhibits breathing because you can't get big valves in the head. If you have that stroke length then a big bore is required to sufficient valve area to support high rpm breathing. They run out of air because the pistons go faster than the capacity of the valve area to supply air. If you put a small blower on it, it could be the best way to go. You might find it is an entirely different motor lol but I just read what wikipedia said about the aluminum 225 and it mentions they're no good for that either due to the open deck. A slant is the kind of motor that you're painted into a corner before you start and the exercise is unpaint your way out as best you can. Hyper pak seems about the best that can be achieved relatively cheaply: en.wikipedia.org/wiki/Chrysler_Slant-6_engine#Hyper_Pak
@@ThePaulv12 I was going to put in a lightweight "T-bucket style roadster" Maybe polish the block, put multicarbs and cruise it. Nothing stressful. Yes I'm familar with all the literature on limitations etc. If someone is interested in it I'm an hour north of L.A.
@@332ARA do it ....DO ITTTTTTTTTT ..btw redline and speeco in australia make some good speed parts for the slant 6...or did
OH! The piston offset thing they mention around 11:00 just solved a mystery that's been bothering me. My daily commuter is a 2000 Honda Insight, and it's always had a lot of piston noise on cold mornings before it warms up. But I remember now that the engine in that particular car has the bore axis offset pretty radically from the crank centerline, in order to give the rod a straighter shot at the crank during the power stroke, reducing friction in the bore. People do this with the /6 by putting the pistons in backwards; the straighter rod angle gives more efficiency but more piston noise. Well my car has a super super gnarly case of that; there's got to be no side load to keep those pistons from rattling back and forth when it's cold. So cool, I'll stop worrying about it.
One of the best 6 cylinder engines ever, not the most powerful, but definitely dependable and durable
Thank you PowerNation for doing this build! I had a '74 dart with a slant 6 from 1988 to 1991 to get me thru school. Ran great and always started, except for when the air temps got below zero. Then I would cross my fingers and hope it would start! Ran it until the frame broke in half on the freeway entrance. I junked it then. :( Again, thanks for this video!
Expect for "great unibody construction", these cars would HAVE KICKED ASS forever!
These were GREAT "kick-ass" American cars! They had style , (GOOD) handling, POWER, and FUN! IF the body/frame construction had been up to (OLD TIME) Chrysler standards, these would have been LEGANDARY.!
I had a 79 Chrysler lebaron that had one of these in it. That thing ran forever.
had an 81 same deal, wrecked the car 4 times, engine kept going sold it with 230k it went to mexico, probably still running
cruizing at 90 mph in my Valiant Regal back when we had an unlimited speed limit here in Darwin NT... loved it
These videos are always incredible quality and so thought out
How to resurrect an engine: 1) Clean the engine 2) Give up and use another engine 3) .... 4) Profit?
um you know you can’t reuse a badly damage block
@@blademaster2701 it still could of been bored out looking it over
extreme reliability , today the engines have a self destruct timer just after the warranty runs out .
Modern engines are way better than old ones. Hundreds of thousands of miles without a rebuild is normal now, it wasn't in them days
@@mrcaboosevg6089 I pass brand new junk cars on the highway every day . Now when you need to repair your car , to get to the alternator you got to take out the Transmission and remove the back seat and rent a special tool to do it . I could kill an engineer / designer .
@@harrytuttle8161 I just changed the alternator on my car, it was a ten minute job. My car is a diesel that revs more than this, makes more torque, gets outstanding mileage and makes more horsepower. Literally zero benefit to this this, it was a good engine at the time but not now
You have a problem....today's cars are far superior to the ones from the "good ole days"!!! Ever own a 57 Ford?
Slant six how freaking cool !! I haven't seen one of those in years. About 40 years ago I had a buddy that had one of those. I think it was a Dodge demon. He actually had a connecting rod come loose. It busted a hole through the side of the block. He took a hammer and chiseled around it. He pulled the Piston down low enough to take out the rest of the connecting rod. He installed a used connecting rod. Then glued down a piece of plywood over the hole. Then drove it for like 6 more months. And then actually sold it to somebody. That person actually bought a car. Knowing there was a piece of plywood covering a hole 😂😅
Solid old engines. I have even seen them come in with a cylinder blown out and still running. After boring it out and installing a sleeve it was rebuilt to continue on for many more years. Well designed engine.
Had 69 valiant did the same rebuild engine was absolutely a beast you couldn't kill it
These came with the cracked manifold stock from the factory.
Ill take that old valve cover... would look great on my garage wall.
In high school I had a 1960 Dodge Dart with the 225 Slant 6. That car was 25 years old when I got it although it had a very kind life. I never had a bit of trouble with the engine (brakes sucked). I did change the water pump out it was wobbly but still wasn’t leaking:) A nice steady power plant very easy on gas and enough speed to get on a highway:) Great engine!
Love the tv show. I missed the straight 6 build with the turbo installed. The black hurse was the coolest. Mail jeep rebuilt is cool too. Keep em coming. Wavin from Watkins Glen new york.
Why use fancy ARP bolts for the sheet metal oil pan, then just use stock head bolts for the head?
because this build's a fail
The stock ones were probably rusty and weren't worth the cleanup.
It's a very low stress engine the Head bolts can more than handle the #)% increase they are giving it. On the other hand the oil pan/pump/water pump just used fairly standard bolts and were commonly replaced with ones with no flange on them or have been overtorqued. they're using the ARP bolts to promote better sealing not for strength reasons.
@@telesniper2 ...Why do you say that? Plus, what would the bolt mfg. have to do with the success of the build? Or are you just wanting to see your bitchy comment on the internet?
@@misery13666 then use a washer and regular grade 5 bolts. Those ARP bolts are incredibly expensive.
Man, you can't beat a slant six. I had a 225 in a 1964 Dodge flatbed PU that I hauled firewood in. I drove it for over a year with a rod knocking. It gave out one day when I had to stop on a hill and it just couldn't get going with the heavy load and top the hill once the traffic cleared. It threw the rod and I just let it roll back into the shop driveway.
You can't beat a 6 cylinder Chevy. You can't beat a 4 cyl. Honda. When you put a tiny engine into a car, it seems to last forever. Oh, so why do we put big engines in them? Because given the choice, most folks want the power!
@Joe Home that's racist.
Thanks for posting the video @POWERNATION it really helpful for bring my slant six 225 back , went over everything I needed to know !
I had a Dodge Dart my Dad helped me buy in my teens Later I owned a Dodge van. Both with this fantastic engine. Later while working as a mechanic I encountered the engine on a myriad of industrial and agricultural products. I know a fellow who installed a Franz bypass oil filter on his and he had over 300 k on it and it was still a daily driver. This is a rare instance where planned obsolescence slipped past the monsters of greed and deception. Thanks for reminding of my long lost love.......... and all the great memories it helped create in my life.
I'd love to see you guys hop up a 318, its my favorite motor that doesnt get a whole lot of love
I'm looking forward to seeing where this goes. I love challengers!!!
“We’re not giving up” replaces the whole block anyway
I had a slant 6 in a 71 dodge demon. Awesome engine,put 185000 on it and was still running good when sold. The engines were really good motors!
I like how he cleans the surface just to run his oils back on the head.
We have 2 slant 6s in our swathers. They are the 225 industrial Engines...Great Engines !!!
Did not expect to see your name pop up on this video's comment section. You and south sask run great channels
@@UncleBubbles94 I like to watch these kinds of videos
@@UncleBubbles94 and thanks
The first car engine I ever took apart was an early 60’s slant 6 that came out of a Valient. I was 13. That was 50 years ago!
