Building a low block 426 for a guy and so far the compression is calculated to be ~9.4:1. .060" over (4.31") with 3.75" stroke and nearly zero deck piston with valve reliefs, small bore chamfer, comp gasket. I'm trying to target about 9.8-10:1 to keep it CA swill friendly with aluminum. If iron I'd be done. Does anyone have any correlation in milling amount vs chamber volume? If I recall these are about the volume of 906 heads (high 80's) but I don't have my notes in front of me. I can get .020" Cometics but would rather chop the heads and use easily obtainable FelPro gaskets. I can get the amount to cut the intake side from the DC book. Thanks.
