That would of been fine if I hadn't of gotten the low mileage 4.8 complete with everything for $300 and it's not stock it now has a cam, springs, pushrods, ls2 timing set, stainless long tubes and some other stuff and eventually it will be boosted. I had considered a 5.3 or 6.0 but I got a good deal on this and I've seen people make good numbers on a 4.8
