Default 968 piston volume

Does anyone know the 968 piston volume?

I know that their static compression is 11:1 with a 968 head. What kind of head are you planning on using?

This is to build a stroker 928 motor. We have the measurement for the current heads and need the volume of the 968 piston.

From the 944 Turbo Board-

Piston volume is 27cc from some recent posts. Maybe someone can tell you on the combustion chamber volume.

Jay,

I have Adam running the calculations since he has measured the 928 head volume.
Thanks!
