Mating A Dodge Cumings Diesel With A Ford C6 Tran

Hey guys.

Does anybody out there know if there is a company that is making an adaptor kit to fit a Ford C-6 tranny to the Dodge Cumings Diesel engine?

Not that I am really looking at making a hemaphradite truck, but arguably the cumings motor is a hell of a lot better diesel out there then some of the used 6.5 and 7.3 International Harvester enginers that Ford used.

Interesting idea.
I have a C6 transmission in my Lincoln Continental. It's been going going strong for 30 years now. Do the 7.3 International Harvester diesel boldt up to the C6?
If gas shoots up to $12.00 a gallon, I just may to consider this sort of engine swap.

I just removed the transmission cooler a few months ago because it was leaking and really don't need since I am not towing anyithing. Perhaps that has prolonged the transmission lifespan.

By chance do you mean a Cummins engine?

topics like this are why people from Alaska fascinate me.. Someday I think I want to live there. Unlike Texans, Alaskans do cool shit with their idle time.. Like make the automotive equivalent to a Centaur.

Are you transplanting the Cummins into a Ford, or the Ford trans into a Mopar?

IMO, it's not worth the headache. You'll have electronics issues - amongst other things. The 7.3 Harvester is a fine engine. It's the 6L Harvester that's a POS. A 7.3 is just about as sturdy as the Cummins B, and for certain years (98,99) much better.

The C6 is, without a doubt, the best built auto trans out there. But no OD; on a diesel don't expect much for a top speed, and your MPG will hurt.

The earlier C6's don't have overdrive.


It sounds like L-188 wants to transplant the Cummins in to a Ford. I doubt Alaska has much in terms of restrictions on emissions so I am sure he can bypass those pesky computer issues.

Where is Falstaff when we need him? I'm sure he and Seb146 and Go3Team can shed some light.

The 7.3 is a better engine than the 6.0. I've heard better things about the 7.3 from a mechanics who regularly change out 6.0 for 7.3. L188 you can still get a pretty decent new or used for the right amount of money.

No C6 has overdrive. The AOD and E4OD were the decendants that incorporated the 4th gear.

The computers in a modern diesel don't just control emissions. Pretty much all light duty diesels went to "drive by wire" in the mid 90s. These computers interface to the trans, insturment panel, cruise control, etc... Doing this swap with electronic engines would be virtuall impossible. With the money spent you could buy a new truck.

 redflag  Nobody does this swap. It would be illegal - the 7.3 does not meet the EPA '02 NOx and PM regulations. That's the whole reason the 6.0L was born.

That's what I've always thought but someone had mentioned that the ones in the F-350 that lasted to 1997 had the C6 with overdrive. I never verified that.

It would be one hell of a headache trying to get all of that done. The ECM on the Cummins has inputs from the transmission, that it needs to run properly. Without these inputs, you might as well just throw your money away.

The older 7.3 isn't all that great. The older Cummins from the same era also isn't all that great. The newer models that Ford and Dodge both have are pretty decent. I've never driven a 5.9 Cummins that they put in the Dodge, but I drive a truck equipped with a Cummins everyday. I am pretty pleased with its performance and reliability. I have also driven my friends F-250 with the newer Powerstroke, and it is a beast. It has plenty of power, and fuel economy to boot.

It is actually an 81'.

I don't know. I still have that truck and I think anywhere else in the country it would be on it's way to the scrapper. But it does have the straight six motor and I do think highly of that one.

I was just trying to come up with a project.

A much more feasible project for that truck would be to drop a 351 into it. If the body is clean and it's 4X4 that truck is worth a few bucks around here, even if it has a tired motor. Do they use road salt up there?

Why not go all the way and drop in a 460cu"?
Mines is 30 years old and still runs strong and very quite. No leaks, doesn't burn oil and always pass California's strick emissions test.

L-188:
Do you have sentimental attachment to this truck? If not, find another one from the same era and same series such as the F-350 or 250 supercab with a 460cu" and keep all shared parts of your 1981 and get rid of the rest of the truck.

By far the best suggestion yet. The 460 is Ford's best and most advanced OHV engine, plus they're easy to work on and parts are cheap and easy to find.

A friend of mine that is an engineer turned airline pilot told me that those engines were carefully crafted and designed with extra attention to detail because they were specifically for Lincoln only back in 1968. They eventually made there way in to the trucks, vans as well as Mercury & Ford full-sized and mid-sized cars years later.
Not sure how true this is but it seems to make a lot of sense to me.

Agreed, but by the same token a 460 does a number on the gas bill. I was hoping for something a bit more efficent hence the difference.

Is the 6 cylinder in a full sized truck significantly better in terms of mileage? How about the 351cu"?

Ahhh...
Well then, why not either update your current 300/6 to fuel injection OR put a later-model fuel-injected 300/6 in the engine bay? No more real power, but throttle response and gas mileage will improve considerably.

Of course if you're going to go to all that trouble, you might as well buy a '95 or earlier F-150: Same truck, more modern drivetrain.

(However, I think the '80-'84 F-150 dashboard and fenders are far more attractive than subsequent versions on the same basic body.)

My dad had a '90 F250 with the 460. It's reliable but I don't think it was all that snappy. Lots of torque, but it was also slow revving.

If you want decent HP without the heavy fuel hit toss a 302 in. They're a dime a dozen and easily modified if you find yourself yearning for more ponies.

Have owned numerous ford trucks with the 300 CI, 302CI, 351wCI. The most durable is the 300ci and probably the best engine ford ever built, gas mileage was in the high teens depending on how I drove it, it was in my 75 ford f150 3 speed on the tree, I miss that old truck. 2nd truck was a 85 Bronco with the a 351 and 4 barrell holley carburator. It had great power with nice response on the throttle with great torque but could not pass a gas station without stopping only had a 16 gallon gas tank. My 90 Bronco had a 302 in it, great fuel milage for that size of engine got 21 mph on a cross country from okc to Colorado springs but hp was suspect, did not have the get up and go like my 85. My 92 Bronco and my 92 F-150 has a 351 in it with e4od trans. The bronco gets 15mph and the PU gets 13mph, plenty of torque. When I have problems I swap parts between the the two to troubleshoot makes it a whole cheaper. Also have a 98 Expedition with the 4.6L, did the last tune up myself, wasn't to hard to get plugs out if you have a long extension plug sockets and imagination, all of my vehicles have way over 100K miles on them and still going strong. prefer the 4.6 to the 5.9 because of ease of mx and gas mileage.
