454 .060 over, bore is 4.311. SRP pistons, flat top.
JE is not specific in their literature for marine use. The only category I thought came close is circle track/drag race that comes out to .0237, top and .0245 second. What is current thinking, less, or add more to both, open second only .003-.005 more?
This a mild build, V-drive Ski/hotrod.
