Heres some specs that I can think of to put on here to maybe make the advice better to get.

- 3.08 gears in the rearend (will switch when I upgrade to probably 3.73 gears)
- 4.3 v6 motor (120k miles)
- auto trans (4l60e im pretty sure)
- 245/60/r17 tires I believe (I think 60, might be 55 or 65, have to look later)
- daily driver truck and don't want to break the bank on gas or mods, just a little beefy v8


I was thinking of doing a cam, cold air intake, longtube headers and maybe a programmer, since I am on a budget I think I can do the headers and cold air intake until my birthday (june) since I have to buy new wiring harness and other engine compartment pieces for the swap.

Any advice would be greatly appreciated and where I could get the best prices, I am located in moore/ S OKC area. Thanks in advance
