How much can i MILL
How much can i MILL I need your EXPERIENCED opinion on this and not "upgrade your cam blah blah".
How much can I mill my 317's? Goin on a stock bottom end 00' 5.3L with a gm hotcam on .550 lift 219/228 .550/.550 112lsa. Keeping stock valve size. Do u think .030 off will be ok without PTV issues?

What compression are you trying to maintain. I guess I don't follow the how much can I mill but i need to keep compression low for FI later.....What are you trying to accomplish?
