A V8 swap in a Bronco? Why not!?

Don't worry, this isn't a muffler post. What do you guys think about a 302 swap for my 88' Bronco II? Going from a 179ci motor to a 302ci seems like a big jump in size, but engine bay space is plentiful, and I have seen it done. It will pretty much drop right in. Provided that all of the stock electrical and what not will cooperate with a v8 instead of a v6. I would remove all of the EFI junk because I want to use a carburated motor. If I went ahead with this swap idea, do you think that I should use the existing trans, or use a matching manual that the 302 was used with? Since my truck has a manual in it, I should use another manual. If it ain't broke, don't fix it! I'm just afraid that a 302 would tear up a v6 transmission.

you MUST use a stang 5.0L the truck motor has a different oil pump and pan, which WILL NOT fit. about the tranny, get a t-5 with a t-case adaptor (it is 4x4 isn't it?) or get a tranny from a fullsize if your willing to do some tunnel mods.

Everybody loves mustangs...

Yeah it's a 4x4. A mustang motor huh? Why not use a motor out of 88' or higher f series truck? I don't know about a mustang motor. This is a local junkyard with cars and trucks no older than 1985. I don't know any place around where I live that would allow a good deal on a stang mill. Like I said, my friend works at the junkyard I mentioned, and he can give me a SWEET deal on a motor/tranny out of a truck. A price like $300 at the max.

i believe the front of your truck is similar to the explorer, if it is, the oil pan will not clear the x member, if it is the earier one, i can't help you, although, i believe they are like the the f-series.

Mine is an 88'

Actually, rangers and bronco II's looked like explorers from 1989 through 1992. Then the ranger took on a different look after 92', and the bronco II was replaced with the explorer in 1991. My Bronco II is an 88' which resembles a ranger from the same years and below. (square headlights) The 302 swap vehicles I saw were 88' or older bronco II's. That brace you mentioned is pretty far away from the sump of my oil pan, so I don't think that will be a problem. But thanks for the tip!

a truck 302 with a 'stang oil pump and pan is the same thing, isn;t it?

Ranger motor instead?

Well I could also drop in a bigger 4.0L. These would be a little cheaper, and if it was out of a ranger, then it would drop right in without a lot of modifications. Yeah I don't want to change the camber with a heavier engine. So I might just use the 4.0L. It will give me some more power than my 2.9L, plus there are more parts available for 4.0's.

A truck Motor usually has a lower compression ration and is disigned for a higher torque outpud rather than horsepower.

the block and guts are the same, heads are different, intake is lower on the stang,(smaller package) there are a few other differences, but those are the main ones. everything is intergangable though.

The upper & lower intake on a 302 are differant for the truck & the stang. The truck intake is "ALOT" taller .About 4" to 5" higher. I do not think it will fit under the hood of a Bronco II. I have seen a Bronco II with a fuel injected engine , but it had a aftermarket intake manifold for a Mustang.

Engine Swaps

There are several afteramarket swap kits available for putting a 302 in a Ranger, and since your Bronco II is the same chassis, these will work quite well. As for the oil pan, I believe they are referring to the double hump pan used on 302's from about 84 or 85 on up in the Mustangs. You dont have to use the block specific as the pan will bolt to any 302. Just be sure to get the dip stick assembly along with it as the regular dipstick which mounts on the timing cover wont work with the double hump pan.
The 4 liter V-6 was offered in Rangers from about 88 on up, so I dont think swapping one of them into your Bronco II should be anymore than a bolt in job as well. IF you elect to go with the 4 liter swap, you might want to consider finding a wrecked ranger with one in it, for a donor vehicle. This will give you all the correct wiring etc, and you wont have to do so much splicing and cussing while wiring the vehicle. When you are done, you can always take the bed, if its any good, and make a trailer out of it, or some such, and junk the rest.

If I remember correctly we made a lot of changes to the Ranger between the Bronco II era and the Expedition. Check with the experts on the RangerStation site, they have some folks that are very up to speed on interchangability. The swaps mentioned are doable, but the amount of work might be a lot more with one combo than another.
