383 build questions
I'm picking up a block and rotating assembly this Friday. It's a 383 kit from Eagle. It will have a 10.5:1 compression ratio with a 64cc combustion chamber. I'm on a budget so I just want to put a set of stock cast iron heads on it. I was told by a buddy of mine that I won't be able to run pump gas with the iron heads and a mild cam. He said I would have to put aluminum heads on with a pretty wild cam or it will detonate. Is this true? Thanks.
Welcome to CHR. I think that you need to hook up your vacuum advance. At part throttle when cruising you have less air and fuel in each cylinder, and the air-fuel mixture is not as densely packed...
