Need help from you ford guys

[ZeroLogic]

I'm pickin up a 92 F150 XLT from a guy at work for 100 bucks. It has a 302 in it now that leaks everything you can think of. And it is also a EFI 4sp with over drive. I looked at a 87 F250 with a 351w in her. I want to rip out the 351w and throw it into the F150. The 351 is carb and coming off an auto truck.

Will the 351w bolt right up to the 302 tranny? I think it would because its practically the same motor just taller blocks. I just want to make sure before I get the F250. Will I need the F250s harness also? I know the intake won't bolt up either but I'll figure something out. Thanks.

yes as long as it's a small block tranny (which the 302 is) it will bolt up. Sounds like it has an AOD in it.

I would triple check to be sure. From my experience when i was building my 79 f250 ford didnt make much of anything to interchange at all. Im a ford guy thru and thru but at least with a chevy you just about know everything will bolt together lol.

I'm just wondering what you're looking to gain. Are you going to make one truck a driver and scrap the other. Is the F250 drivable now? And why wouldn't you just rebuild the 302?

[ZeroLogic]

Thanks for the replys. The guy I'm buying the truck from (bros girlfriends dad) talked to a transmission guy and said it will bolt up.

The F 150 I'm gettin for 100 bucks from the guy I work with. There is some surface rust on some welds and thats all. The 302 leaks antifreeze from a few places, and oil from a few other places including the rear main.

The F-250s frame is a cheese grater. The only thing work touching on the truck is the 351w. So instead of rebuilding a 302 I'll just go with an 351w for more power. If you catch my drift.

If I get the F 250 I'll just rip out whatever I want and junk the rest.

Isn't the 351 carbed? its gonna be tough swapping a carbed motor into an efi truck but its easier than the other way around. you'll need the 351 gas tank because of the efi fuel pump. among a lot of other things.

[KXRida]

Not nessicarily a hard swap. It's usually more time consuming to swap an efi motor in than a carbed motor. Keep the kick down cable off of the carbed motor... trust me, they are a mother to find.

[ZeroLogic]

What else would I need to swap it. Is there a book I can find or a article on the internet? I can't find **** online.:ermm:

[extremeblastr]

any particular reason why you wouldn't use the parts from the 302 to make the 351 efi? everything about this swap is bolt in and go and the intake and what not from the 302 bolts up on the 351

believe or not, check out therangerstation.com and some other ford sites' v8 sections. Lots and lots of great info any swaps. I say the ranger forms because 95% of them swap in 302's or 351's. More 302's than anything though.

More 302's than anything though. agreed! also i could check and see how much it would cost to just rebuild that 302 thats in there. if you can do a atv you can do a car motor... i checked on a 2.8 V6 ford and that was about 160 OTD with gaskets and all that... thats all the bearings, seals everything piston rings... and then it would be about 20 bucks a bore for me... so i would have been at so im at about 280 give or take 20 bucks...and a few hours of work...

Put a 350 sbc in it. :p But in all seriousness from what I have heard Ford is not known for being interchangeable... They have like 7 million different engine/tranny combo's.

Most small block fords run a C4 or AOD. A large percentage of the transmissions work, but the bell housings have to be switched. You also run into the issue of transfercases with a truck, but that's more of an issue when you're running a manual. An NP205 or 208 bolts up without a problem to a C4 or C6.

i've spoken to my father about this also (circle track racing fanatic who has built many of his own and other peoples cars) the motors and trannies in question are very interchangable. like i asked earlier why are you not switching over the efi setup from the 302 to the 351? everything there should bolt right on.

The fuel rails will, but you may need to change injectors. Also you'd need the computer out of the 351 donor truck. If the transmission will bolt up to a 351, it will bolt up to a 302 and vicea versa.

i was told you can swap the setup with at worst the purchase of a computer out of a 351 efi but that it should run fine with the computer from the 302.

the 302 will usually run it, but most people that do efi use the entire system. If you have it, know it works, why change it? Hell a 2.9 computer out of a ranger will run an efi system on a 302/351.

yeah i know lol i was just simply making him aware that it was not necessary for him to purchase a computer he can do a direct bolt in swap of that motor with 0 changes other then adding the efi from the 302 to the 351
