See that's what I don't get the pistons have a slight dish yet people are crankin out 9.5:1 with 87 e heads. 455s are a bish I guess. I think the ram air 400s came with 72 cc but the 455s had huge combustion chambers like 115 but I think compression was 7:1

. Theis is for the 73 by the way. 72 is getting ripped apart and getting powdercoated awaiting a lq4 to take down george.
