If you look at my mods, what would you do next. I don't have the money for PI heads right now. I think I have 3.73 gears. I am about to do a full tune up and Dyno it. I am thinking King Cobra Clutch, then short shifter?

 

Okay, a few ideas would be:

1) Verify the gears. If they are 3.27, then up the gears to 3.73 or better. Usually a tag on the diff cover.

2) Headers. LT or shorties, your pick. LTs make better power, but can be a pain during transmission work.

3) Plenum and throttle body. Ebay for $245 polished.

4) Is your timing advanced via computer? If not, advance it 4-5 degrees or until you start to hear detonation. Whatever grade fuel you tune to, you will have to use that grade or better. Tune it to 93 and you're stuck with the pricey gas forever.

5) Control arms for the back end. If you're making the power, you need to be able to put it down. CAs help a lot.

6) PI swap. Save up and do it right. Have the heads and intake ported and polished and get a quality valve job done. If you want to add cams, there is no better time to do it. Yeah, big $$$, but worth it.

7) Or, you could save your pennies and put the FRPP S/C setup designed to bolt on to a stock 4.6 with 6 psi but it's not intercooled. About $3K (plus install).

The funny thing about the FRPP setup is that they only claim 55 HP from 6 psi. KB say that there S/C delivers 106 on 6 psi. Granted, KB has a cooler, but that is not worth 50 HP running 6 psi. I think the Ford numbers are too low. I think it is closer to 90-95 on that charge. Thoughts?

 

if you dont have the money for the pi heads then just swap in the pi intake man.

yeah make sure which gears you have and get new ones if you still have stock
long tube/ equal length headers
dont get the throttle body and plenum unless you are sure that you will go forced induction, way too much money for like 2hp
