Has anybody done one or know of one? This winter I plan on doing RGR/JPC stage 3 Heads with big custom Cam's locked out especially since HP broke the code and these motors can be pulled to 8500....it's crossed my mind to put high compression pistons while it's apart....I run E85 full time so I would want 13:5:1:-14:1. I personally think 575-600rwhp is very possible on this setup. Let me know if you guys know of one.
