Compression Ratio

Anyone have the formula or care to figure this out??

52CC combustion chamber on a stock LT1 shortblock with a GM gasket.

If you know, or can find out, the stock deck height and piston volume then you can just use the calculator right here on this site.

Well, it looks like everything is already on there except for the piston top volume. Anyone know this?

Most of those values are not for a stock LT1. BTW the stock stroke is 3.48 and the stock gasket thickness is .049. Hope this helps.
