Hello folks, I am a diesel guy so pardon my ignorance of things with plugs and wires.

I have a dear friend who has a 1992 f250 4x4 with a 302 in it.
It died a horrible timing chain snapping, rode throwing death yesterday.

He also has a 1996 f 150 with 351 in it.
He was told that he would have to gut the electrical in his 92 to be able to swap in the 96 351.

He was also told that the only direct swap he could do is if he found a 92 302 only engine (not 91 or 93 Etc...)

I am hoping to find a good answer for him on what to do.

Can he swap out the 302 for the 351 without having to build a new truck?

How hard is it?

Thanks everyone. I appreciate your insights.
-Chris

 

This write-up from another Forum may help dispel those myths: 302 to EFI351 swap

 

No this is all totally wrong, both motors will plug right in and any 5.0 would work including one from a Mustang or Explorer. The wiring in the '92 does not have to change at all, the 5.8 is essentially identical to the 5.0 in terms of sensor locations and such so that motor will literally plug right in as far as wiring is concerned. The big issue is the transmission in the truck, is it a manual or automatic and if auto is it the all mechanical AOD or the EEC controlled 4R70w or E4OD? If he has a manual or AOD then he needs a 5.8 EEC from a manual or C6 auto truck.. a common combo in the late '80 to early '90's, but if it's one of the others he must get an EEC for that exact engine/trans combo. If the truck has a 4R70w then that's really bad because there were no 5.8/4R70w combos from the factory. Otherwise the swap will require a 28oz flywheel or flexplate for the transmission in question.. can't use the 50oz version currently on the 5.0, and some exhaust modifications will be necessary because the 5.8 is wider. So bottom line is if the truck has a 4R70w then a 5.8 isn't easily done, if that's the case then look for another 5.0 instead.. preferrably one form a '94+ truck, Explorer, or a Mustang. To use the Stang or Explorer 5.0 the truck intake, oilpan and pickup, and accessories will have to be swapped on.

 

thank you very much guys. I will report on how the project goes.
