Cummins Conversion, 89 F350 4x4

Hey Guys, first post here. I am looking at purchasing an 86 F350 CC 2wd that has a complete 12V Cummins Conversion done to it 20K miles ago. It has a solid rust free body but does have some body damage.

I would like to buy the truck and use it as a doner for my truck (see sig)

They both have a C6 Trans, and both were Diesel trucks before. The only difference is the 86 body style to 89 body style. But there weren't many differences in the driveline.

So my qestions is will the Cummins fit in my engine compartment wihout having to move the trans, transfercase and GearVenders overive back a couple of inches? that is the only thing that I am worried about. Everthing else should be on the doner truck that I will need.

It sounds like the 86 was done professonally and everything works on it (tac, air, etc) so everything that I would need for the conversion should be there.

What do you think?,..

If it is complete and reasonable it sounds like a good deal. I bought a complete 96 2500 4x4 for my 78 Ford CC conversion. Makes all the differance in the world when you have a complete donor. Finding brackets and assorted hardware will give you one heck of a headache if you don't already have them!

Yes you can install the Cummins into your truck without moving everything back but you will have to ditch the mechanical fan and put in electrics which I have heard a couple guys have heating problems with.

Is the 86 running a mechanical fan? If so, they probably moved every thing back at least a couple inches.

If they are the same wheel base, just transfer everything along with. Worst case is that you have to work the driveshafts, that's it.

Ok Here is the deal, First of all Thanks for the replys and input so far! :thumbsup

Here are the pics of the Doner Truck: 1986 Ford F350 Crew Cab SRW, 2wd that has had a 12V Cummins Conversion about 20K miles ago.


1986 Ford F350 Cummins 12V pictures from friends & fun photos on webshots


I have been driving it for about a week and it runs and drives excellent. I did all of the tweaks on the pump and that made a real difference in performance.

It looks like I will be moving everyhing back a couple of inches to clear the oil pan to crossmember. The same has been done on the doner truck. Shouldn't be that big of a deal, I will just have to lengthern the front driveshaft, and shorten the rear.

The Doner does have a mechanical fan. They moved the trans crossmember from the front bolt to the back bolt, and drilled another for the rear of the crossmember. Should be the same for my truck as well.

The problem with that is that my truck is 4x4 and the doner is 2wd. Plus My C6 is pretty built and has a real nice shft to it.

So take a look at the pics, the motor is a Cummins Reman with 20 K on it. It is not Intercooled but I do have one that is going on the truck once the conversion is started. There are pics of the IC also. It is a Hypermax Intercooler designed for the Ford Trucks so I will have to get creative with the IC tubing to make it work. But it is a real nice Bolt On system for my truck.

That is the latest, I really like power of the Cummins so far and cant wait to put it in Big Ed!
