David and I are arguing a point lately, and I thought I would ask you guys. What is that deck clearance on a chevy 350 block that is untouched with stock pistons and rods. Oh yeah the block is 1972 block.

Around .025. All blocks are a little different so a measurement is necessary, but .025 is a reasonable ballpark figure.

Okay, So I was right! David swears that deck on a stock block is .015, and I told him that would be after the block has been decked 10 thousandths. Now, I am can set up my Excel program to figure compression ratios. Thanks guys.

you were right all right, and with a shim head gasket your piston to head clearance will be just right.
