You might be overcammed since you only have headers.

more useable power can be made out of a 4.8 with a much smaller cam.... try something in the 212/216 range... nice power and it will idle and drive a little better...

You also need other supporting mods. I bet you would like that cam more with more mods. Do you also have a decent exhaust after the headers? What about a tune?

I know you are pretty much over cammed with that 4.8, but you would like the truck much more with those mods. After that think about 212/216 or even a 216/220.

Look for something around these specs:

212-216° (~266° @ .004) intake/214-220° (~270° @ .004) exhaust duration
.530-.550" lift
110°ICL
112°LSA
