Well no more 2v in my future. Picking up a 4v from a 04 navi for 700. The npi/pi monster is on its way out. Only 80k on the budget rebuild but has begun to lose compression. Cyl 1-3 are right at 148-152. Cyl 4/5 are 138-141, and cyl 6-8 are stil 168-173. So time to start planning a all motor, reliable torque monster 4v.

Thanks. I already know which direction I will be going. I'd like to find a Cobra R manifold and run that over the stock Navigator unit.. But I will have to find a way to keep longtubes.. May have to cut change the angle on the headers and then reweld them with the proper flange.. I want 350hp/350tq to the wheels minimum all motor on pump gas..

Does your truck have the 4r100? If not just use the PCM from your truck and get an Sct tuner.

No it doesnt have a 4r100. I have 4r70w but I'd need the wiring harness for an older model navi I think because the one that came with my engine has 3 big plug ins like the newer model trucks do.

I think you might be right... I talked to a guy who did the swap on another forum and he said to reverse the polarity on the cops and that's it. His is 2001 f150 crew cab.

Turns out all you have to do is switch the COP polarity and you can use the stock 2v wiring harness with a tune on the pcm. Saves me some trouble... hopefully lol
