What I am trying to figure out/find is an aftermarket piston that will raise a 400b mopar with in the neighborhood of 10-1 to 10.5-1. I read alot about the 451 motor, but want to keep the stock stroke. If I were to bore out the block to an oversized 440 piston, what would I have to do about the deck height? I am also running 452 heads. Not finding alot of info, so any bit will help. Thanks
