LA360 compression

Ok, I'm spending way too much time on this but that piston sits .111" down in the hole at TDC using Silvolites own numbers. Taking that info and using UEM's own calculator to figure compression, I got 8.4:1 using a .039 thick and 4.250 bore head gasket and a 68cc chamber. All those are only guesses since I have not measured chambers or have the compressed thickness or gasket bore info.
