1995 F-150 Engine Swap?

1995 F-150 Engine Swap?
My grandfather has a 1995 F-150 4x4 LWB with 302/5.0L V8. He only uses it to pull a fifth-wheel camper. He doesn't like how it pulls and wants to do a engine swap in it.
He wants to do a 460/7.5L swap, and I've done some digging on forums and found some people say that nothing is required. I've also saw where people say you just need new motor mounts, and some say you need a new bell housings etc etc.
I don't know much about Fords but I think doing a 351W swap would be easier since it is not a big block.
Any information you guys can offer on either swap would help loads.
I don't know what kind of transmission the truck has under it, I crawled under it and the transmission had this as a tag on it:
PKF-C3
F4TP-BA
057644
Thanks!

Well for 95 and a 302 it could have been optioned the E4OD with 20 pan bolts and door jam sticker TRANS code E, or more commonly the lighter 4R70w with 14pan bolts and code U. Either way, they won't bolt to the 460 bell pattern. You are correct in a 351w will be a more simpler swap as it will share the 302 bell pattern. Either way, you still will need a donor truck to steal the wiring harness and computer as the '94+ 302's are MAF, and as far as I know all 460s were speed density, along with most models of the 351w.
I'd sell it, and buy a 250 to start with for the easy factor. I imagine there will be the rambling posts of that a 5th wheel is probably overloading the 150 and you should trade for that reason, but I do like the idea of big blocks in light trucks to go real fast with.

Thanks for the reply! I went over there and it is the E4OD transmission. The 460 is out of the question now, due to the different bell house pattern. But he is still interested in the 351W.
I found online where someone did a 351W swap and used the factory 302 harness for a 1995. http://www.fordtruckclub.net/forum/s...ead.php?t=2190. Would this be a good template to follow?

i swapped out my old 302 for a 351 in my 95 f150. since yours is MAF it makes it a whole lot easier... all you have to do is pull the 302 out, remove the engine wiring harness from the motor, put it on the 351, drop the 351 in, and done.
heres a link to my thread

so far i have about 10K miles on the swap with zero issues, pull trailers 2 or 3 times a week.

It's not the firing order that matters
S/D systems use batch fired injectors so the injectors do not have to be sequenced to match the ignition firing order like they do on sequential fire MAF systems.
That does matter is that the 351 will be consuming 16% more air than a 302 and the fuel system will need to supply 16% more fuel. That will run it right off the fuel/air/spark map which typically will accommodate values that are 12% or less out of the expected range.
Will it work with the 302 processor? Yes.
Will it have anywhere near the performance that it should have - and would have with the 351 processor? Not a chance.
Will it go into limp home mode to protect the engine from going lean and burning pistons? Quite possibly and if it does it will drink like a sailor on liberty.

Thanks for the help the truck is a 351 truck by vin
Like I said new to EFI been building 514 stroker and did a roller 5.0 in my 67 I just bought this truck and my friend I got it from said when he bought it, it had a crate 302 from Autozone it has a lifter knock and smokes with only 54,000 on it the vin on the trucks says its a 351W model we don't know if the guy who put the 5.0 in it changed the Processor might be why this 302 has so much *** cuz its running the 351 Processor how can you tell the two apart? Thanks for all the feedback

thanks again
Im going to pull a head bolt off first to see if its really a 302 or a 351 one the 302 intake since there are forms about how to swap out the bigger port intake. I'll also check the numbers off th processor. The guy who had it before him had a shop do the engine cuz the windsor in it took a crap so maybe they did it right if not its ok processor from the junk yard is $35
