Yea I know the rear has got to be swapped out eventually...At first this motor was going in my camaro and now since we had the 383 out of the chevelle we decided to slide this motor in as its been on a stand and not ran since 2004...I had a 12 bolt I was going to build for the car but I donated it to my uncle that has a 66 chevelle since he is painting my camaro for me.

Your math doesn't add up here.

12 cc dome
3.75 stroke
64 cc head
4.155 bore
.041" head gasket

zero deck 14.6x:1
.060" negative deck (.101" total piston to head clearance) 12.19:1

Are you saying your pistons are around .050" below the deck?

What does work out at 12.5:1 is the 70 cc chambers, an undecked block, and 12 cc domes. (Vic Jr's come both ways)
