You can't calculate the compression ratio from that data. The compression ratio is a calculation of the volume of the cylinder when the piston is at bottom dead centre in comparison to when it's at top dead centre. The data ought to be in the manual, what engine is it?

Wikipedia says 8.3:1 to 9.8:1.

The 8.3:1 would be the lower power version with a carb and the 9.8:1 would be the higher power fuel injected version, I'd say.

You'd probably have to go down the route of getting the high compression pistons and modifying them or having some custom ones made.
