418 cubes, 65cc heads, .039" thick, 4.14" dia gasket, 0 deck and 23cc dish will net you 9.9:1 comp, 20cc will be 10.2, 15cc will be 10.7.



It'll be 418 ci, 63cc heads, .035" thick & 4.125" dia gasket, 0 deck, 21.5 cc dish. The CR will be 10.3 to 1... I am probably going to run the 20-230-4 comp cam. Should see about 450 HP at 5500 RPM and 500 tq at 3500 RPM. Agree?
