Hello all,
I was playing with the idea of building a turbo 425 BB olds for my g-body cutlass. But i'm not quite sure how to approach it... what special things need to be concidered etc. The 425 olds did have a forged crank which should provide ample strength below. But what else needs to be in place or helps a carb/turbo setup perform. I figured this would be the best place to ask people with experience from the early GNs. So.
what type of cam profile does a turbo "like"
what compression is recommended...
special carb?
cylinder head prep?
anything else i should look at before i attempt this project?
thanks
