ok...so what would be the best cam for the 4.8? Besides the cam what else am I lookin to change for about $200-$350 for a noticable gain in HP? I'm an electrical guy, I know how it works and what it consist of but I have never turned a tap on a motor...besides electrical stuff

if your planning on stay NA i would go with a .220/.220 .581/.581 112lsa with a circle D reworked TB stall. Might need a 3200 stall. When you do the cam you need to go ahead and vale springs, and pushrods. Might as well while you are in there.
Found my cam used for 250, Valve train upgrade was 430 and the stall is about 350 and before or at the same time as this you need a tune from Nelson Performance!

will that cam work with a factory stall?

it would work alot better with a stall, you might loose some low end without one

220 range sounds good... I would invest in some gears like 3.73 or 4.10s and a stall first.
