I'd like to thank everyone that helped me decide on the compression ratio for my current project on this thread: Ported and Milled Vortec heads on stock 350
As mentioned this is not my engine and as a result of the comments; I will take a conservative approach with compression. The chambers measured 65cc before milling, target after milling 62cc. Estimated compression ratio as follows, 0.5 less than my original target:
Cylinder Head Volume (cc) 62
Piston Head Volume (cc) 10
Gasket Thickness (in.) 0.026
Gasket Bore (in.) 4.166
Cylinder Bore Diameter (in.) 4.0
Deck Clearance (in.) 0.030
Stroke (in.) 3.48
STATIC COMPRESSION RATIO 9.53:1
Two Singh grooves were cut in the chambers as shown, I will post better pictures after the mill and valve job.
