For argument sake, ( yes, 400 with 400 rods and 440 crank), what kind of compression would this combination have? I don't think I'm using the calculators correctly. 1.6xxx isn't even close so I know Im doing it wrong or leaving something out. The 400 block would be squared at 9.980. CH on KB 1274-40 flat top pistons is 1.812, 400 rods and a 440 crank. We'll say 90cc chamber and a .020" steel head gasket. I used the calculator incorrectly but, I'm thinking this piston would be sticking out a bit.
Thoughts?? TIA
