Just thought I would throw in some really old info. In high school I drove a 60 chev pickup with a 235, and with the help of one of the top tractor pullers of that time (1970) I put a corvair turbo on the truck, first I used the corvair carb,for two reasons, It was on the turbo and I didn't have any money! For some reason that I still don't understand it got terible mileage so as I was able to I got an adapter from whitney and used several other carbs, a 550 holley worked best I belive because of all the jet options. At times I ran as much as 20 psi boost but of course broke a lot of stuff, head gasket first, then pistons, but I never damaged the lower end. this is also my plan for my 49 soon.
