How big of a difference does a cam change make on a basically stock 02 v6 (cat-back, CAI, (Chip in future) cause i thought i read somewhere it was a smart investment on 99 and aboves. I know nothing about changing one but i see supersix sells one for stock springs/heads, would this even make a difference. Then they offer regrinds, is that just taking your stock one and redoing it, and do i need new rockers or anything, blah blah blah.... and so on. So if someone could explain it to me I'd really appreciate it.
THanks !
