RV 440 Comp ratio

[tdenkler]

Does anyone have any idea what the comp ratio is on an RV 440?

Does anyone know how much I would need to shave off heads for 9.5 or 10-1 ratio?

Thanks,
Tom Denkler

Typically, 8.0:1.

With zero other changes, this piston calculates exactly out to 10.1:1
Shaving heads to the safe max won't get you there plus you have to shave the intake manifolds.
