Thanks for the information, I did some more searching and found from several places that 76cc is indeed the chamber size on the 255hp 350 with 9:1 CR
I did some calculations using an online calculator, if I retained the same deck height, piston design, head gasket etc, the 64cc would give a static 10.29:1 CR
which is right where I wanted to be.
I have however given in to the fact that a crate engine will be my best bet, given what I want to achieve.
Thanks
