Well yeah I want to make it a 383 ok now thats just the begining what else would or could I do to it to make it push out more h/p? Ive heard that making it a 383 I want to keep my flat tops and not use domed ones because the domed pistons would be just defeating the purpose of making it a 383 but why? If not domed pistons how you gonna get very much more h/p with out using any kind of boosters like NOS, Blower, Supercharger, etc?
