Hi Guys,

I thought I would show you my recent score. I've been looking for a Bronco project truck for quite a while now and got this 92' a couple of days ago. It has a 351/E40D. There is no rust on the truck, even on the tailgate! The only dent is where the swing away tire swung too much. It runs strong and the trans shifts better than my 90'. The interior is pretty ratty, but everything seems to work except the A/C. All and all, if I put a paint job, seats and carpit in, it would be a nice ride. I have other plans. This is the start of a build thred that will probubly take me about two years.

 

Here is the Cummins 4BT I plan on installing with a C-6 trans. (The 351/E40D will be set aside for a spare on my 90'.) This engine came out of a bread truck and has about 70,000 miles on it. This picture was takin after a little cleaning.


This is a D44 I got from a junk yard out of a 79' Bronco. Got all the mounting hardware and steering links. It was really rusty, this picture is after a lot of wire brushing and some spray paint. I only cleaned up the outside. It will have to be completly gone through. I plan to install new gears and locker at some point. but it rolls fine and even appears to have tight steering joints.

 

nice, this could be fun haha

 

Nice... very nice!

 

Love to see another diesel Bronco lol! Man Ford should have offered it as an option from 83 on. I bet it would have been a decent seller.

 

Very popular swap in the Early Broncos, should be great in the full size. The solid axle is badass too. What kind of lift/suspension are you shooting for?

 

My plan involves stripping it down to the frame and mounting the engine as back as possible and then doing SAS. At that point I'm going to figure out the body. I'm probubly going lift it about 4-6 and 38's. I got some more ideas, but I cant reveil all of my evil plan just yet. HA-HA

 

so what is an average cost for the 4bt?? and do you need an adaptor to fit the C6?what kinda power do you get out of that little fart?

 

that motor tends to run about $1500+, the adapter plates can cost up to a grand also.

power wise if you turbo the motor figure 250hp and 400lb torque

 

I feel dumb for asking this but oh well. Are there companies out there hunting down the bread vans, sort the good ones and part them out or do you have to scrounge for the engine yourself? That engine looks really clean. Has it been refreshed or just cleaned and painted?

 

I bought this allready pulled. It's cheaper if you buy the truck and sell it for scrap. (Theres about 1500 lbs. of aluminum in one of those trucks.) But you have to separate it. I dont have the time. Kem is probubly right about price, But I paid quite abit more than that for the engine. If you think that engine looks clean, wait till you see it after I painted it! I'll get pics next time I'm off. You can make those engines get about 200 hp pretty eazy. Some people have pushed 500 through them. But even stock (120 hp) the torque is very high at low rpm.

 

AWESOME project!! I strongly approve!

The only thing I didnt like about using the C6 behind the Destroked adapter is the fact that the C6 did NOT just bolt right up. I had to cut out a section from the bottom of the bellhousing to clear the flexplate. I haven't gotten around to welding in a bulge to cover the missing section yet, but I plan to at some point.
Now I'm not sure if the C6 from a diesel will fit better, but I suspect that it will. If possible, get a shell from one and try it out before you get it built. If I'd known all this beforehand, I wouldn't have used a normal gas C6. But destroked told me it was a bolt up, and it wasn't even close to that.
The adapter and billet flexplate will cost you about $1500, and the quality is incredible. I can't imagine a motor nasty enough to break these pieces, not even a 18-wheeler could hurt them, I bet.
The vacuum setup to make the C6 shift isn't a big deal, either. The VRV valve is available through Ford for about $120, and you will need to make a bracket and shaft to mount it to the throttle. This setup shifts like it's computer controlled,(minus the headache) and is even better than the vacuum setup in a gas motor, because it has greater adjustability. You can really fine tune the shifts.
If you have any questions, feel free to send me a message anytime, or just ask in this thread. (I will be watching this build)

p.s. Make DAMN sure you check the timing case dowel pin, to see if anyone has secured it. This is the one and only Achilles heel of the early Cummins. It's called Killer Dowel Pin, make sure it's fixed.

 

70,000 on a Cummins is barely, and I mean barely, broken in. I had mine apart to fix a cracked timing case, and with 159k miles on it, the internals looked like the motor had just been built. A rebuild for a Cummins like this one means a can of spray paint.

 

Thanks Thunder,
I allready got the adapter and flexplate from Destroked. I put them on so I could start it and check the oil-p. (65psi) They are of nice quility, But I had to grind on my engine block to mount the starter. (it is the starter they recomend) I just hope the C6 bolts up. (I dont have it yet.) I'm going to have that same outfit build mine that you used. It is going to be a small bell C6 because it's the same as an E40D. That way if I get to bogged down in this project, I could just throw the engine in my current Bronco. I have got alot done on the engine including the KDP fix. If I get a slow day at work I will upload some pics.

Does that vacume thing have electronics in it? I was thinking of haveing them just make the C6 a manual shift.

 

You might consider using another E4OD behind that 4BT.

The OD and locking Torque converter will give you awesome mileage!!

Just get one of these: E4OD and 4R100E Performance Products

I'm bolting an E4OD on the back of my 292 Y-block and putting it into my 55 F-600. With the E4OD and 2 speed axle, I expect it to run pretty good!!




Cheers,
