I wanna see numbers. Word of mouth mean pretty much **** all to me when I'm dropping bills on performance parts. Its why I have not bought a converter yet. No numbers I can find to justify the purchase. Same thing with **** like a power wire. Unless I have concrete proof it means jack all.

here is a kinda updated list. there are things that are not on the list that have done good and there are things that should be rearranged on the list as well.
NO on the throttle body spacers. They are meant for a carburetor motor. I would recommend
1. Ported Throttle Body
2. Cheap things like E-Fan, and a new Y pipe. TMR mod is free do it. (use the search function)
3. Headers, only option is shorties for the 4.7
4. I would then do Superships. I am not sure how much difference you would see being a stick and although they do do SOME motor tuning. They focus on the Trany
5. If thats not enough Gears, (The gear choice will depend on what size tire you are going to run most likely a 4.10 or 4.56)
6.2008 H/o intake manifold
7. Under Drive Pulley
8. Then a Torque convertor
9. Then Ported and polished heads
-While you are doing this you might as well do cams, high lifting springs and all those goodies
10. CAMS
-KRC is now offering full billet cams with LSA ranging from 116 to 106
11. Now that you have a cam and new heads you are going to need a custom tune. I would only recommend one tuner for the 4.7 Hemifever
12. For you custom tune you will need a wide band gauge and maybe a couple others to get the info he will need to tune you correctly.
13. If this truck is still not enough for you I would look into a lowering kit to run smaller tires
14. At this point if you still need more the only option is to leave the world of N/A, and at this point you have 3 options
1. NOS-has been run on a 4.7 before that ran good times
2. Turbo charge, KRC is selling a kit with everything you need 2-3k
3. Supercharge, you will be hard pressed to find one. They made one
years ago for the 4.7 but discontinued it. You will see them come up
for sale every now and again.
This list is just my opinion over what I have heard, learned, and witnessed working over the years. If I am not clear or you got any questions post it up!

Braggadocio. The phenomenon that occurs when admittance of total satisfaction is expressed after several hundred dollars have been spent even though results may have been disappointing. Its not that I do not trust people I just wanna see actual values that are numbers not well this is way better than before comparisons if you know what I mean.

To the OP - What are you goals for the truck? Are you going to run it at the track? Just looking for a little extra pep for day to day driving?
