I just want to verify my calculations: I have a 355, 30 over, my pistons are 10 in the hole and my heads are milled to 64.1cc's. What do you calculate my compression to be?

What is the compressed gasket thickness? (.039") Need to know the size of the valve reliefs and the size of the dome if any.

-Mark.

Mark, The heads are AFR 195cc heads 2.02 intake, 1.6 exhaust which were 74cc combustion chamber milled to 64.1.

My pistons are flat tops 2 valve releifs. Standard stroke.

Sounds a whole lot like the one I'm building, right down to the .010" in the hole. I calculated it at 10.31:1.

Glen,
Whats your build up?
