Hi, I have a 2005 4.7L that I just paid off. I would like to make some upgrades now that I have the money. The only upgrade I currently have is that I stripped the muffler and added glass packs for a free flow exaust.
What are the best performance upgrades I can get without taking my truck to a professional mechanic? I should be to do most engine work.

1. 4.56 GEARS - depending on your tire height 410's/4.56's. Personally if your tire hight is taller then 30" tall I would lean towards 4.56's.
2. ELECTRIC FAN - FLEX-A-LITE 180 FREE = 10RWHP ... You have a factory electric fan which will keep everything cool even without the clutch fan.
3. 2008 INTAKE MANIFOLD or our SULLIVAN ALUMINUM INTAKE MANIFOLD -
4. 4.7L PERFORMANCE CAMS - H/O's, 206's or 212 Cams Im a fan of the factory H/O cams in HEAVY trucks or trucks that will be used for work or on the road oe when torque is needed most.
5. SUPERCHIPS FLASHPAQ - Great with up to 70mm throttle body and H/O cams.
6. HEADERS -
7. SINGLE 3" EXHAUST -
8. HIGH FLOW "Y" PIPE & MUFFLER -
9. 70-72MM THROTTLE BODY - F&B. Chose the largest Throttle body you can tune for. (70mm for Superchips & 72mm for SCT custom tune)
10. RACE PORTED HEADS -
11. CUSTOM PROGRAMMER - SCT CUSTOM TUNE (Needed with PORTED HEADS & or 206, 212, 212x, 218 or greater custom cams & or 72mm throttle body)
12. 2800 STALL CONVERTER - This will get you off the line quicker by allowing your engine to rev to approx 2800 before the transmission engages... Under part throttle would would not notice much of a difference at all... but put your foot down and the RPM's will rocket to the desired RPM getting you closer to your RPM power band.
If you have any questions please feel free to contact me.

I got mine from AIRRAM. For the Efan, I have a writeup I can send you. PM me w/your email. I can't attach anything here... AIRRAM beat with the Comp Cams link. They should be coming soon. If they are as good as the 206 cams or better, we should be in good shape!
