Looking for Info / Specs on Obsolete Mopar Piston

With the OP gasket thickness of .044" and the piston flat being .010" above the block deck like he says, the Eagle calculator shows 11.3 to 1 compression ratio.


That sounds correct. But because I have "issues" and I have most of the tools here at the shop, I stuck the piston out .050 and milled the dome down to get 11.08:1.

As of now, my quench is a bit loose, so if I run into detonation I'll pull the heads, use an .039 gasket and make it 11.25:1 and close the quench up a bit.
