New motor mounts, new brackets for accessories, new transmission or trans adapter.
If it were EFI then you have to do all that swappin too.

I am sure there is something I have forgot.

windsors suck, why would you want one?

but yeah, you would need alot of stuff. and stuff you cant buy. headers would be tough, would prob have to use manifolds. motor mounts, trans, etc like listed above.

LOL yeah maybe i was drunk. no, i dunno, it was just a thought about a windsor since my block is tore up. i dont really wanna do a 460 swap although that would be awesome. anyone got any M blocks laying around? :wacko

My parts truck had a 351M/400. I don't think its any good, sounded like it had spun a bearing and its just been sitting...but if you wanna mess with it, I'll see what dad says - like if its worth coming to get. :shrug

I've got both a 400 and a 351 in east tn. They both need head gaskets. $50 for the 351 and $75 for the 400 if you pull. Add $75 and I'll pull and have it ready for ya.

Couldn't you use headers for a F-150 4x4 302?

"Couldn't you use headers for a F-150 4x4 302?"

Good luck finding some.

Ford didn't put the 302 in a 78-79 bronco or a 70s 4X4, i don't even think they put them in 4X2 F250s and 4X2 F350s either. I have never even heard of a F250 or F350 with a 302 VIN code.
The 351W has a 1.3" taller deck and that could cause clearance issues with "F150 4X4 302 headers".
Incase you're wondering why ford didn't put the 302 in 4x4 in the 70s. It is because ford had motors that would do the job better like the 300I6, 360, 390, 351M, and 400.
In the 80s and 90s ford only built four engines 300I6, 302, 351W, and 460 so they didn't have much choice.

Raised from the dead thread pile, cause I searched and
had to read this trash.
So some one wanted to know about the above swap,
and didnt really get an answer.

Which is a reasonable question , as the 351W is a common engine,
a dime a dozen.
First thing is motor mounts will be changed if not fabricated, or frame mounts moved and then
the pre-"M" series C-6 will have to be ditched for a Windsor series C-6 bell housing. (I beleive) So the trans mounts will have to be changed.
Some one who has done this should dump a link in here on the match up at least to get things started. Thanks.

Im thinking of doing this with a 85 Windsor too a 1979 Bronco, and maybe ill come back to fill in some blanks.
Right now im moving on to find a 460 answer. "Cheers"

i thought the 79 came with a 351/400m ?

It did, but the two different 351's that it was offered with were the 351C, and the 351M. The 351W wasn't an option in 78-79 Broncos.

There are many more performance parts for windsors than M's. Not to mention the windsors have better heads and are a lighter motor. They also make a dang good race engine (http://www.badasscars.com/engines.html). They were able to provide me with plenty of info on the M vs. W engines.

I checked into this while deciding on what to do with my 79 build. The windsor is cheaper to build peformance into. However I decided on a going the 429 route so I havent researched what all is needed to swap in a windsor.

Neither was a 351C, only a 351M.

Do a google search for the Moss brothers. They race a 78/79 with 351W or search www.thewebwheeler.com they have a forum just for the Moss brothers.:thumbup

you pretty much got it really. Me and my friend took a 315W out of an 86' bronco and put it in his 79 f-150. We used the motor mounts, the bell housing, all the accessorie brackets, and exhause manifolds off of the 86. then it went together pretty easy

I would think that the Cleaveland style heads are better than the windsors.
They have canted valves and are used more often, when given the choice, for building high horse power circle-track engines.

Then put some Cleveland heads on a Windsor and build a Clevor. ;)

Ford already did put Cleaveland style heads on a Windsor. They called it a Boss 302. Was used in 69 and 70 Mustangs.:duh

im pretty sure the 78-79 came with the 351W along with the 351C and 351M

No, only the 351M or 400, only 2 motors offered in 78/79 Bronco. Unless of course you have the ultra rare 300 6cyl.

This thread is exactly what I logged on looking for today!

I major part of the reason for my wanting to put a 302 or 351W into my 78 Bronco is EFI. I was going to go with a throttle body kit, but everything about it didn't seem worth while.

Then I strated looking for 351M parts. Yipes, talk about expensive and hard to find!

The 351M in my 78 is a mystery. It is clearly a rebuild, and doesn't sound stock (little loopy). So, I would have to do so much work to figure out the cam in it, etc, that I figured I should just put a new cam. Yeah, right. Nothing with the specs I would like...

Plus, who knows the condition of the cam bearings?? So, then I would have to change those, which I suck at and usually bring the block to someone for... so, now I'm pretty much taking the block apart.....

So, this long winded (typped) story brings me to the final question, has anyone ever actually done this before?

I can certainly see how it would be fairly easy to get the motor and tranny into the truck with relative ease. But, how about the drive shafts and transfer case? Are they all the same?

It looks like any drive train should pretty easily swap from any of the 78-96 broncos, or so I have read. I have still yet to talk to anyone that actually has done it. I have not been able to find much about the brothers, except races they have been in and/or run.

Everything I read tells me that the frame and wheel base is the same for all broncos from 78 to 96. So, I should just have to take the motor and tranny mounts out of an 85-96 5.0 EFI bronco and I'm good to go. Comments?

Some interesting disinformation in this thread. Anyway yes the 351W can work in a 78/79. We made our own mounts because they need to be stouter for racing but there are easier options I believe. Contact Bronco Graveyard and Autofab by phone they will know. The trans does not need to change positions but you have to get a small block case c-6 if you are auto or change the bellhousing for manual. The better engine is the one you have the most parts for. I think the frames are narrower than the later model broncos so I am not sure you could throw the entire drivetrain with 1356 t-case in there from a later one without lots of work. I have wanted to install an injected 351 and E4od in one of mine but havent the time and would want to keep the 205.
