Compression Ratio Help Please
I have a stock 02 bottom end LS1. I will be installing GMPP (65cc now) heads with stock gaskets and would like a CR of 11:1. What should the CC of the heads be? I figured 62cc by using a proportion, but the calculator is giving me a different figure.
I will also be installing a comp 222/224 .566/.568 on a 112.
1. What should the pushrod length be?
2. Any concerns with PV clearance with this set up?
3. Is 11:1 CR too high

If all you want to change is the chamber size to get to your goal 11:1, 62cc will get you 10.95:1... assuming you are .007 out of the hole and you are using the factory composite gasket.
