By the way i don't really want to go into engine internals. Also how does the rest of the drivetrain hold up to that. If i buy Z it will definately be a stick. I know i will obciously need a better clutch. With 400 RWHP what kind 1/4 times will it run?? I do ocasionally do a little street drag racing. And would like to beat the shit out of a Z28 with a "wussy V6 car" as they like to say. I already paln to go stage III plus headers and JWT NOS on my 90 N/A.
