Hi Everyone, I have a 1956 F100 and a 4.6 with a aode from a 94 Mark VIII and I want to run this engine and trans with Corvette C4 suspension front and rear. The first question is do I try to use the Mark VIII EEC IV PCM and rework the Mark wiring harness or is there a better aftermarket chose? I kept everything from the Mark, so I still have all that stuff. If aftermarket is better who make the stuff? Would I be better off going to OBD II 96-98? How do I tune this? I want to be able to drive it daily
Thanks

 

Why go through all the hassle and expense this will surely entail? A 4.6 is wider than a 460, just do a mild 460 with E4OD or ZF5. Surely easier and cheaper, and lots more power. Just something to consider.

 

Well, he has all the Mark VIII stuff already

Use the stock harness and PCM, I'd say. Tuning it, well, that's a different story.

If it were me, I'd go for something later with flash-capable PCM. I don't think the '96-97 will do it, not sure about '98. You'll need a chip to insert into the side of the PCM to do any tunes for it, and the '94 will surely need a chip too.

 

now this is my opinion but, if your looking for a easier swap and possible avoidance of the swap headaches, look to ford racing. they have a 4.6 control pack. believe it comes with a ecm and harness. that might be a viable avenue to check out. also, have you checked with painless????? they might have a harness then just round up a puter if your running a manual or a non-computerized trans like a aod or c-4. as ar as that hanress you got from the car, you might run into more headaches than ease of install.

 

Find a Crown Vic frame and graft it onto the F100 frame....it's easier than you may think. Then the 4.6 should fall right into place. The Mark VIII is already one of the better 4.6's out there, so I would use all the stock wiring and ECM.
