Just so I'm clear, you believe that with a 4.0 inch stroke and the 4.0 in diameter pistons that I have, my compression will be 10.68 to 1 with the magnum heads that I have since they actually measure 64cc's? I guess iron heads would be out of the question then for pump gas?
If my math is right and I just used the stock crank 3.58 my compression ratio would be 9.67 to 1?
A 3.79 stroker crankshaft would bump the compression up to 10.17 to 1?
Right, there is some assumptions in there (Head cc, deck height) but close enough.
The other combos would need different comp. height pistons
for example if you used them on a 3.58 crank you'd be .249 in the hole
swept vol. 737
deck vol. 51
valve pocket vol. 4
gasket vol. 9
head vol. 64
865/128 6.75 to 1
So I am assuming you mean the correct corresponding pistons.
