Jim, no I'm starting out with a 4.360 bore, I really don't want to go much faster. It will be a 496" 4.15 stroke with these heads, cam, lifters and belt drive from the "Frankenstein" motor so it'll make less power but be 150 to 200 lbs lighter so it will probably another .10 faster still. I'm keeping the compression around 12:1. I may be off here but I've always thought that compression above 12.5 is harder on parts and makes power but not enough to justify to the abuse to me because I want to put a lot of passes on the motor without major maintenance. But that's just my theory I've picked up from my machinist. But I agree you need much more compression to make much more power.
Okay, now your losing me. The New engine was going to be a 526 ci. with 12.6 comp.
But now its a 496 with 12.1 comp.???
Your heads flow more then that stingy flow bench shows as others have mentioned.
