If anyone is interested. I have a brand new 2004 5.4L with the auto transmission still attached. The engine is complete with wiring harness, accessories (alt, belt, A/C, ..), exhaust manifolds, and fan. This was removed from a brand new unwrecked F-series.
Package has less than 200 miles on it.
Thanks,
Kevin

 

Kevin,

Is that the new 3 valve 5.4 with a 4R75W tranny?

JMC,
Yes, you are correct. New 5.4L 3 valve with 4R75W transmission. They are still coupled together. Flywheel, starter all included, also. Might have computer.

Actually I have just finished reviewing the pinouts for the 4.6 and the 5.4 pcm's for the '98 model. It appears that the 4.6 pcm will have to be used. The pinouts for the trans are different. So just run the 2 coil packs with the sparkplug wires.
As for the engine from the '04. You will need every wiring harness and module from the '04, also you will have to add 4 wheel abs, the dash will have to be changed so you can put in the instrument cluster from the '04, see where this is going? Good luck to anyone trying that swap.

 

i would go with that 4.6 from that wrecked truck. might not even be a bad idea if you really want a 5.4 to look for a wrecked truck with the 5.4. the money you save would make a lot of sense.

 

Here is what Mike Troyer came up with.

He told me to get the PCM from a 98 with the 5.4 which he said I could get from any dealer, just don't pay over $299 for it. He said some dealers try to gouge on the price.

Next SuperChips is coming out with a new MicroTuner which he is getting trained on the software for next week. He said it should be available by the 15th of Oct. This is not the Max Tuner, it is a new tuner. He can custom tune to the new 5.4 to maximize for the PI heads.

The PCM from a 98 5.4 will match my transmission and I won't have to deal with PATS. I will be able to use the COP instead of the Coil Packs so won't have to change the harness. Mike also said to make sure the PCM is for the 4R70W transmission as that is what I have.

Mike didn't have a price on the new tuner yet, so will hope it isn't too expensive. He did say the truck will fire and run fine with the PCM from the 98 5.4, but will not be taking advantage of the PI heads so I will want to custom tune for that. The new MicroTuner will just flash the PCM and he recommended it over a Flip Chip.

The new motor shipped on Friday, so hope it will be here by the end of the week. I will look at the harness and check into the PCM once I have it. Worst case, will stay with Coil Packs instead of COP and get the MicroTuner. I will update as I get started with the swap.

Thanks again for all the useful info.
Steve

 

I don't want to contradict what Mike is telling you, but I am almost 99% sure that in '97 and '98 the 5.4 was not offered with the 4R70W. Being the weekend I cannot research it completely. But I cannot find a pinout diagram for a '97 or '98 5.4 with the 4R70W. The only way to really find out for sure is to ask my parts guy on Monday. I'll check on price for you and see how much I can get it for at my cost. I'll let you know.

 

HI!... Ford has always offered the 4R70-W tranny from "97" to current with the F-150's. 4.6 or 5.4. That was the tranny that FORD used in 90% of the auto applications.

 

Hi Neal,
I didn't say that the 4R70W wasn't offered, just that it wasn't offered with the 5.4, but I will find out for sure tommorrow.

 

Thanks SVT and Neil! I appreciate the help. SVT, let me know what you can get the PCM for. That would be great if you can help me out with a better price.

Steve

 

HI!... It was offered with the 5.4. The 4R-100 was only offered in some of the 4x4's and the CALIFORNIA emission packages. My father had a 4R70-W in his "97". There was also the spiecal 4R-100 with some desiel internals that was install only in the LIGHTNING.

 

Well sclime,
My parts guy says there are no pcm's listed for the 5.4 with the 4R70W trans in '98, but if someone that thinks they more than I do can come up with the calibration code off of one of those 5.4 4R70W pcm's, then I can research further. But since I am so uninformed, I am just going to stay out of it and say keep the 4.6 pcm and the coil packs and get a chip burned. Later.......

 

Thanks SVT for looking into it. I think I will take your advice and stay with my PCM and the coil packs for now. Easier to have a chip burned than trying to change to something that doesn't exist. Since I will have the wiring harness from the new motor, I can always research that as an alternative later. Besides, the flip chip will most likely be cheaper than the new MicroTuner.

Thanks for all the assistance. The motor should be here by Friday.

Steve

 

Steve,

I will be cheaper to follow svt's advice.
You already have the old engine wire harness and the PCM. Swap them over to the new engine and get a chip burnt for the new motor. You will save the price of a PCM. It should run with the 4.6 PCM but it will not run as well as it could.

JMC

 

Thanks!!!
I contacted Kar Kraft and the 5.4 is a 2000/2001 so will have the PI heads. I have contacted Mike Troyer and will either have a chip burned or look at the new Micro Tuner. If the motor will run as is, I will at least be able to get back on the road and then add the chip when Mike is back from Florida.

I'm picking up the flywheel today.
