Calculated compression ratio with 10.7 kit

Calculated compression ratio with 9.6 kit
Static 9.67:1

What stroker kit would you recommend?

Given that you'll be using 95 RON octane (91 US octane) I'd recommend you go with the lower 9.6:1 compression ratio.

Does anyone know if there is any virtual engine dyno program thats any good to test out compression and cam combos ?
