Many years ago I was involved with a company that built quite a few hi-performance Corvairs. 10:1 compression, increased lift/duration cams and increased CFM induction systems. In those situations the best advice I would give is to replace the cast iron exhaust manifolds with tubular headers to reduce head temperatures. If you don't you will be plagued with valve seat failure. Also install a hi-volume oil pump and a large oil cooler mounted in the right of the engine compartment with sealed ducting from one of the inlets on the right forward of engine compartment and outlet down above the exhaust area. A manual switched electric fan is also very helpful. An oil temp gauge revealed that prior to these modification we were running temps around 300 degrees, after 180 degrees.
This video makes a very good point that EVERY Corvair owner should know. It is very important that you put a block off plate on the right hand side of the top shroud where the ova hose goes through the firewall. On turbo and air conditioned cars it is over in the centre more but equally as important to be blocked off.
It should be blocked off because the air that blows into the cabin is valuable cooling air that is supposed to blow past the hot cylinders and cylinder heads. When the air blows into the passenger compartment instead of over the engine, the engine will overheat. It's pure common sense
Depends on what gas you get where you live. Advance it until it pings and then retard it til it stops. the mark may get out of line due to the 2 piece pully
Good video, Flat6. I just came across this. I know...late. Glad to see another Corvair driver with a bike rack on. I currently have 2 65 4-doors and drive one daily. In Ca. now, but moving to North Georgia soon. See you around.
Excellent video. Picked up my first Corvair about 6 months ago. This video has been very helpful. Thanks
Thanks for a great video how do you clean the oil cooler fins thank you

Why blocked off instead of left stock to get air to the cabin blower?

And always have a spare belt
Very informative but, the photography was terrible. Turn the camera so it fills the screen.
hey what should my timing be on a 64

Nice video Noel!
I hate peep hole cameras!!
