Ok, but the bottom line is this is a half ass budget build. I wasn't aware that there were such crappy piston choices for 383's and that 906's were essentially useless.

My setup, with the parts I listed, with a block that's been zero decked, KB flat tops (with the 5cc or whatever size valve reliefs), closed chamber 84 cc Edelbrock heads and a .039ish head gasket sounds like it should make decent compression and quench. Does that sound about right? I'm just hoping for a decent street motor.




What is your definition of DECENT COMPRESSION ?




I think you know more about it than I do, but I was thinking 9.5-1?




That number is obtainable but the thing is the aluminum heads pull so much heat out of the combustion chamber you really need another ,5-1.0 points of compression to start taking advantage of them....
