I removed the .50mm and .25mm cylinder base shims and installed a 1.00mm shim and did the math again. I now get a TDC dome height of .879".
So .670" + .879" - 1.498" = .051" in CM = .12954 cm. 1.29mm deck height.
Bore x bore x .12954 x .7854 = 10.174 cc (V2)
518.364 + 10.174 + 89.9 - 46.76 = 571.678
over 10.174 + 89.9 - 46.76 = 53.314
Equals 10.72:1 compression ratio.
That's more like it. I could get the deck height down by removing some piston dome volume and go less that 1.00mm cylinder shim but I think this will be fine.
