Make sure my numbers are right on this [MENTION=76842]Carcrazygts2[/MENTION]
I still dont know if im going 2v or 4v. But I need to order pistons and rods to get the bottom end done.
Considering the PI heads have 42cc chambers and the 4v has 52cc has made me deliberate on the pistons. The block was bored .020 over, so bore size is 3.572
Going with 18cc dished and the 2v with give me 8.94 (static)
Going with 18cc dished and the 4v will give me 8.11 (static).
I think both of those would work either way I went.
