Henry - my race 2.7 has Mahle nominal 10.3 CR pistons I bought from Andial many moons ago for my twin plugged motor. When I Whistled the motor the actual CR was only in the high 9s, probably because I didn't measure things and adjust when I assembled the motor. I thought they were RS pistons, but maybe they were RSR?

Elgin 315s and 46s gave 220 RWHP. Very tractable motor.
