This is what it looks like when a Corvair engine comes apart at high RPM.

i drag race air cooled vw motors at high RPM i found out the best way to make a air cooled motor live at high RPM is a forged chromoly counter weighted crankshaft. using forged chromoly i beam connecting rods .i dont know if they make the above cranks and rods for a corvair but it sure works on my 300hp vw race motors i built over the years great vid

I would guess ran low on oil, spun a bearing & broke the rod. Back in 1970-71 I had a 1965 monza (140HP) with 7 qt finned aluminum pan, headers & glass packs, cam and 4 primary carbs. Regularly turned 8000 rpm on stock bottom end.

Quite the variety of nuts on the upper cylinder studs - looks like they reused some of the rocker stud nuts.

Thanks for the video, I love seeing motors that have self destructed!

interesting video, I'm not that familiar with classic cars so seeing a cool motor like that and some carnage in it is pretty cool!

Rod bolt stretched, bearing shell rotated, journal starved of oil hence the blackening.

That intake log on the heads didn't actually make much more power than the stock head. He would have been better off using bigger valves and adding a second port to the stock heads and then using 4 carbs on it. It would have worked and made just as much power without that weird log manifold.

Bad design! IDK what some people are thinking?

When you throw a rod in air cooled stuff case will suffer. 6500 rpm wow

"Typical sandrail stuff" The folks I have met running sandrails tend to be mechanically insensitive and taking shortcuts on engine builds is totally on brand for them.

Put some Carillo "H" beam rod in it.

And yet #1 is closest to the oil pump. Were the crank and rods from a turbo or 140hp motor, they're stronger.

This appeared to be a conglomeration of non 140 parts. Thanks for the reply. Mark

Too bad. That may be one of GMs best engineered engines out of the gates. SBC was a fluke and not that great out of the gates and the 3800 was a multigenerational stepchild. Corvair motors were a curveball.

Sorry, but intelligent People do not rev these engines up to more then 5500 rpm, so they last for a long time-

Hs anyone put a Porsche 911 engine/transmission into a Corvair?, These engines are made to be revved! I owned a 3.0 litre 911SC for 5 years, loved every moment of driving it.
