Well I was looking at throwing on a set of 302 heads on my 273. They turned out to be 308 heads. My short block is running factory bore 2bbl pistons zero decked with a felpro gasket (4.06 x .039) I believe. I'm not looking forward to the compression drop as I'm looking to go with a better/bigger cam. I got a few leads on some commando pistons (10.5:1). I can't seem to find a way to calculate my compression with the 10.5 pistons and 308 heads. I was just trying to guesstimate with published chamber cc numbers but still unsure. Also I plan to use a gasket with a (3.7 x .028) with the 308 heads and 10.5s
Where will I end up roughly compression wise with this combo?
