Default Bronco II 5.0 swap

Any one put and explorer 5.0 in a B II I know there is alot of write ups out there and I have read most all of them. Just seeing if there is some one else on here that has done it that I could shoot questions to if I run into problems along the way. Its going in a 87 B II with a np435, np205, d44 and 9 inch 4.88 gears and 37 mtrs. shoot me ideas of things to watch out for if you know of any.

If you are putting in a solid dana 44 up front you can use a regular fox body Mustang oil pan. I am running 35" boggers, a Dana 44 up front with a 9 inch outback with 4.56 gears from a 77 Bronco (last year of early small Bronco). Also if you run a body lift you can avoid cuttin the heater box to clear the valve covers. I did not use an Explorer engine because I did the swap in 1994 before V8 explorers where made. For a trans I am running the stock 1984 C5 and factory BroncoII transfer case, I just changed the bellhousing. Even though everyone said the the t-case would fail, 16 years later and lots of abuse it has givin me no problems. If you have a specific question just ask.

Im in the middle of doing the same swap but Im using a 94 EFI mustang 5.0,c4 and my stock t-case in my 90. How do you have your motor setup as far as the front dress and rad/core arrangement?

I am using fox body Mustang serpentine set up and I bought a custom radiator that sits inside the core support. The radiator and motor mounts I bought from Total performance, North of Detroit, back in 94. I don't know if they still make them. If you are keeping the stock front axle you will have to modify the Mustang oil pan to clear for axle movement on one side.

Im installing a EB d44 as well rite now. I am trying to use the same front dress and I have a 94 Ex rad. I was going to cut my core support out and make a new tube one moved as far forward as possible.

Default Bronco 2

When I did mine I used a 351W it was a sqeeze but it went in . I tried lots of aftermarket parts james duff / advance adaptors / hedman headers and what I found is that like mentioned before the stock B+W 1345 T case must be indistructable never had a problem with that . The advance adaptor motor mounts were actually stock fordf mounts from something and set the motoe in there just right so worth the money the AA headers though were junk the hedmans were very nice fit even for the 351W they were meant for the 302 . I used a C4 tranny and the AA adapter kit never had an issue with any of that . The stock front end remained but it was the weak link . The rear end didnt make it the 7.5 just wont do it . I used an explorer rear end you have to move the spring perches to the top of the axle and center the axle up before welding back on it ended up like 3 inches wider not a big deal I was running mickey thompson 32x14.5x15 baja belted tires and finally the last part that had to go after watching it bounce down the road a few times in the rear view was the rear drive shaft it just wasnt going to hold a V8 . I modifyed a full size bronco shaft and made that work that was the end of any troubles I had with that truck with the exception of overheating once in awhile at silver lake whrn running it really hard . I had cut the core suport and moved everything forward as far as I could then used a perma cool black magic 2800 cfm fan that did a pretty good job unless running it very hard . I have lots of experience in this swap so any questions Im here to ask too . I still have the truck just the body got really bad I have another body just havent had the time nor ambition with all the other projects to start on it again .
