Big Bronco FAQs
#91
I might be a little late of a reply so idk if anyone told you this but I heard that long tube headers aren't so good since it would be boiling your oil if I recall? It was something with oil but I suggest you put in shorty headers.

If so, that depends entirely on what gear ratio you have in your differentials. What is your ratio?

Moderators, can we create a sticky like the 80-86 bullnose section has, or delete posts on here and lock this thread? Or maybe a how-to section? Then post actual FAQs and answers? i.e. tell new members to use the search function, then start a new thread if they can't find the answer, and how to post pictures. Also talk about 460 and diesel swaps, 4 door broncos, SAS swaps, soft tops, how f150s and broncos are the same from the doors forward, and things that are different between trucks and broncos. We could also post links to build threads that have the answers to common problems. I have lots of information that I would be willing to write, and others could add to if you wanted to?

I'm going to start posting info, but it would be nice if we could move it to the first page.
Did the bronco ever come with a 460 or diesel?
NO, it never came from the factory with one, but it is a very common and popular swap.
The 460 was available in 2wd 73-78 trucks, and in 2wd and 4wd 83-96 trucks. Therefore it can be a direct swap. I don't know the exact info for 78-79 broncos, but will edit later if I find it. To put one in a 80-96 bronco, you will need the correct/aftermarket motor mounts, transmission, wiring harness, radiator, and cross member or an oil filter relocation kit. I haven't had a problem with my truck, but others have reported that their front suspension can sag from the weight of the 460.
Putting a diesel in a bronco: there are 4 popular swaps, 6.9 IDI, 7.3 IDI, 7.3 Power Stroke, and the Cummins. The first 3 were available in Ford trucks from the factory. They are just like the 460, and require the correct cross member, transmission, wiring harness, radiator, and core support. Bronco suspension will not hold up under the weight of a diesel, and require the axels and suspension to be swapped as well. Diesels will also fit in 78-79 broncos, and there are many build threads of IDIs and Cummins swaps in the 73-79 truck section.
460s and diesels were available in 4 door broncos however...

4 door broncos were made from 87-96. Production numbers are around 4000 total. They were not made by Ford, and were aftermarket conversions. Centurion, Magnum, and Metropolitan were the bigger companies. there were also a few limo companies that did conversions. Each company had different names for them. Centurion made the most, and also made the crew cab F150. There were 2 types, stretched broncos, and f350 crew cabs with a bronco rear added. The stretched broncos frames were cut and lengthened, and the F350 based ones had shortened frames. They were built to order, each one was different, and were available in half ton and one ton versions. They were available with rear heaters, and are known for having rusty roofs. There is a forum dedicated to them with more info here:

This is a sticky. The web page in linked on the first page is the purpose for the sticky. Admittedly the website has not seen an update in quite some time but the purpose was to alleviate the volume of repeated/duplicate questions that this particular forum used to field on a DAILY basis at times. Modifications are not emphasized on the site simply because they are personal preferences and not facts about the Bronco. In short, the intent was never to create an end-all be-all listing of information about modifications, uses, and variants lest the forum not be necessary.

im doing a transmission swap on my 1992 bronco, 351 Windsor, electronic 4x4.
Had E40D putting a m5r2 in, the issue im having is the clutch hydraulics. i have a new master, new line, and new slave, seems to be very hard to bleed. but i have noticed that there were little things ive had to do to get things working such as, the pedal did not travel far enough to release the clutch cut some of the pedal assembly to allow more pedal travel worked for a small amount of time. i have also noticed that the slave cylinder that is "made" for this isn't big enough, after bleeding system only got a 1/4" of travel in the slave then realizing that that was the the end of the slaves travel. i then put in some spacers behind the slave separating it from the trans and in return it increased the travel of the slave cylinder. what could be wrong with this?
the bell housing to deep?
wrong slave? wrong trans?
have tried multiple bleeding procedures including bench bleeding both master and slave cylinders i am at a total loss i think i could still use more pedal travel but again im not sure, but it still doesn't make sense that i would have to have spacers inbetween the slave and the trans to get more travel
