How much compression before I change pistons? Hey guys I have a fairly new 383ci ls1 will 10.8:1 compression that was running 6.0 heads and and ms4. I want to run a single mount setup but I am wondering if I should change pistons or run e85 or meth. Any help would be helpful. The whole bottom end I'd forged and could take the boost aside from changing the rings
