Ford Interchangeability
Hi guys, I'm new to fords, and need some information. so thank you in advance!
Ok, so I have a 1995 Ford F150 shortbox reg cab 2 wheeler with a 302 with a mass air flow sensor and the same firing order as a 351 (im told this was odd???) and an automatic overdrive transmission. Not sure what kind it is. The engine leaks coolant out of a few different places (stored outside without any coolant, only water by previous owner) and I want to swap in a 351 out of my 92 F150 4x4 ext. cab. auto. My 92 has suspension damage from an accident, and is undrivable, but the engine/transmission/t-case is undamaged.
What I want to do is bolt the 351 up to the 302's transmission. Not sure if it will even bolt up. The 351 doesn't have a MAF sensor, so that is an issue i will have to address, as well as the oil pan/etc.... What kind of problems will I run into with this type of swap? will it even work???
Thanks guys!

From some of the other members on here, dont be pissed if I am wrong though, but you can used the 302 wiring harness on the 351 to gain MAF on the 351. The MAF will adjust for the larger displacement 351. Now the tricky spot is what is the trans in the 302 truck? Is the AOD-E/4W70 or the E4OD. If its an E4OD then you can swap with no issue. If it is the AOD-E/4W70 you will need a different flexplate to attach it to the 351. You could use the flex plate from a late 80s crown vic that had the 351/AOD combination to do so.
One more option is to take the entire drive train from the 92 and convert the 2wd to a 4x4. It will take more time, and a little more work than just an engine swap.

All 302 engine 1994 and newer have the 351 firing order and they are an SFI engine.
The transmission is more than likely a 4R70W.
The 92 is a bank injected engine and more than likely had a E4OD transmission.
That all said the 4R70W should blot up to the 351 with no problem. The big problems you are going to have is wiring and the injectors.
Are you going to with the 95 computer or the 92?
This subject been covered a lot of times so do a search and it should tell you what you want to know.

I just checked and i think its the AOD.....so I will need a flexplate from a Crown Vic that has a 351/AOD? is there a website that I could buy one?? part number??
The suspension from the 4x4 truck is messed up, The swing arm is bent, and a couple brackets are broken so I would be in the same situation trying to find a front axle, then swapping it over etc...so I don't think that that is an option at the moment. Plus, this truck would look great lowered. It doesn't have a speck of rust on it, and the paint and interior are great...keeping it 2x is what i am going for.
The wiring harness will just swap over like that??
Thanks!

ok....it is the 4R70W...lol, I figured it was the same thing as the AOD-E/4W70....but like I said, I know nothing about fords. I am planning on using whatever computer will be the easiest to use! Which injector setup should I use??? will the SFI work on the 351? I'm just looking for the easiest most strait-forward way to go about doing this. I have both complete trucks sitting side by side, so interchanging parts/wiring is not a problem.
So I won't have to get a different flex plate??

I did a search and it is all so confusing, and everyone has different answers for the same questions...lol.
So this is what I have got so far and tell me if I am right. The 351W will bolt to the 4R70W, with no issues. Next would be wiring up a computer to control the 4R70W and the 351.
-can i adapt the 95 computer to control the 351W?
-or would it be easier to adapt the 92 computer to work with the 4R70W?
I'm not going to switch fuel injection systems unless it is strait forward...I'm not going to modify anything too much, or buy any custom setups etc..
I have the full exhaust from both trucks, so that isn't a problem either.
so mainly its the wiring/fuel injection that is going to be my biggest hurdle. Anyone have an answer that would be tailored to my situation?? What about a custom "tune" on the computer for the 351/4R70W setup? what would that run, and would it be worth it?
What about using the MAF on the 351? would that be an issue...
I know I am being difficult, but I would like to get this done before the snow flies, and i don't want to beat around the bush.
Thanks!

Another option I have, is sell both auto tranny's, the t-case, and other parts and raise money for a 4 or 5 speed manual, and then problem solved. Which manual transmissions would bolt up to the 92 351W?? Thanks

Your swap is relatively easy, you just need the complete 5.8EFI motor from the '92(oilpan to throttle body) and a 28oz 164 tooth AOD/4R70w flexplate, do not use the one on the 302 it's 50oz or the E4OD flexplate from the '95.. it will destroy the 4R70W the first time you fire it up. Both motors use the same engine mounts and tranny bolt patterns so the 5.8 will physically drop right in with the right flexplate and connect to the electrical system and fuel lines. The mass air system doesn't need any help to run the 5.8.

I think he is also saying to use the '95 PCM Computer and all of its engine wiring and you will be running the 351 as a SFI, MASS air engine.
The PCM computer must match the 4R70W transmission and you may want to JB weld the Knock sensor to the engine block as the 351 does not have a place for it.
Let us know how this comes out.

That pretty much answers my questions on the fuel injection, lol, thank you for that. So i still need to find a flexplate. I will probably go and talk to the local transmission shop and see if they can find what I am looking for, unless someone can give me a link that I can order one. Thank you all for the help, and I will let you know how the swap comes out!

Yeah.. short version is don't use either flexplate you have get a new one.
Yes correct.
There may be a spot down on the skirt at the back you can use for the knock sensor, though it will have to be drilled out and tapped larger. If not leaving it off and the connector hanging won't cause big problems.
The spot I'm talking about is visible in the pic below.. that's my 5.8 block getting cleaned up.

Is there enough room on a 351 block to drill and tap the flat just behind the intake manifold (top center of Paul's picture)? I would try to install the knock sensor as close to the 302 location in the 351 block as possible.
