LQ4 Compression, piston selection Can anyone help me figure out what pistons I need to run with this setup to make or get as close as possible to 11:1 compression. I am thinking flattops with -2cc valve reliefs.
LQ4 block bored .30 over
PRC 5.3 stage 2.5 heads 220cc
Chamber size: 62.5cc
Stock GM gasket .52
4.030 bore
3.622 stroke
Cam is 230/232 .613/.595 on 111+1LSA
Thank you!

That is pretty much what I'm doing, except that I'll be using an MS3 cam. Static compression will be exactly at 11:1. Hope to make at least 400 rwhp through a stalled auto... I do foresee a lot of tire shredding in the future...
