A buddy of mine wants to put the 5.9 turbo Cummins in his '75. Been looking on craigslist but wanted to know other than obviously dodge pickups what other vehicles/tractors/equipment/large trucks came with the 5.9 Cummins? Like stuff we might find rusting on someones property and we could just go make them an offer?

 

Medium duty Ford F650's and F750's. Medium duty Freightliners, Peterbilts, Kenworths. Don't know about any of the medium duty Chevy/GMC trucks.

 

You have to watch out for the F series Fords the Louisville series trucks came with the 5.9 Cummins so a L-7000 or L-8000. The older FL-50-60-70 Freightliners do have 12 valves but most of them are 24 valve.

Any engine out of a medium duty truck would be rat bagged the 12 valves in a medium duty usually are only good for 124,000 miles.

Also look for old retired school busses some came with 12 valves.

 

some of the checrolet P vans had the 4bt in them. they also had an aluminum body. People where uying them for the engine for aswap and then selling thealluminum, back when scrap metal prices were high. I had not heard that the 12 valve cummins only lasted 124k. there are a lot of cummins swap sites out there. I know Destroked.com is one for cummins in fords

 

Fork lifts, generators, motorhomes, busses. Did they make a 24v engine that was non electric like the 12v

 

I think you want to stay away from the engines that were used for generators etc. they are not as ruged as the ones in the trucks and will not last in a vehicle.

 

I know some school buses had 5.9s

 

how hard was it to get your cummins engine in your truck? I know they are great in a ramcharger, probably even better in a bronco. What tranny is that attached to? Is it a ford tranny with a bellhousing adapter plate?

So, I know for a fact that the old ford bread trucks used to have the twelve valve 5.9 litter cummins. The 12 valve are better in my opinion. They are in fact more mechanical so to me more reliable plus, easier to change parts. The 12 valve 5.9 L inline six is a great engine. Many people like them more than a 7.3. Last I knew you could get bellhousing adapter plates to use these engines with a borg warner t-19 or any other ford tranny. Really great if you ask me. There is nothing wrong with a cummins powered ford if you ask me. Great frames and suspension to make a great work truck. Its like a 300 Inline six, only its not a 4.9 liter, its 5.9 liters, its not gas its diesel. Quite a reliable engine. They can out pull a lot of things.

 

I could be wrong, but I thought the bread trucks all had 4BT Cummins in them..

I put the motor in my Bronc without removing the core support. But I used a forklift, so I could lift it way up high when I angled it. The 5.9L fit better in the Bronc than it did in the Dodge. The Ford has a nice firewall indentation and I actually mounted the drivetrain 4 inches rearward of the stock location. You can buy mounts if you don't feel like making them, they're pretty cheap. I had a performance C6 built by Dynamic Racing Transmissions in Connecticut. They put a 6.9L diesel governor in the C6 and set me up with a 1200 rpm stall speed billet torque converter. You have to clearance the bellhousing on the C6 in spots to clear the aftermarket flexplate. The adapter plate and billet flexplate came from Destroked, and are of amazing quality. You can read through the whole process in my build thread, here:

There's videos and such, too.

I would have to say that the frame of the Bronco is far stronger than the frame of the Dodge that the Cummins came from. For one thing, the Bronc frame is fully boxed in the front section, and the crossmember is a smooth welded in heavy piece, whereas the one on the Dodge was a bolted-on angle iron piece and looked like part of an old bedframe.
I prefer the Cummins over a 7.3 for a few reasons; 1, it's an inline motor, which I like more than a V8 in a truck. 2, the stroke on the Cummins is 4.75", where the 7.3L has a 4.18" stroke. The inline 6 is incredibly easy to work on, you can almost stand next to it in the truck, there's so much room. I love that.

 

You are correct. I just looked it up. The bread trucks did in fact have the 4bt/ 3.9 liter inline 4 cyl cummins. It seems to be the little brother of the 6bt or 5.9 liter cummins. Very neat. Glad your project went well. I love a diesel inline engine my self. I am a beginner diesel technican so I love this stuff. I like the inlines better as well. Thanks for the info. I do in fact look foward to doing a project like this some day.

 

just an fyi the cummins in the durge p/u was a slighly different engine. they are front gear set vs the conventional rear gear engines found on evrything else.

 

They are no different in terms of ruggedness.

The injection pump on a stationary engine is different and will not work in vehicle application. For this reason, and the need for accessories, correct oil pan, etc. they are not a good choice for swapping into a vehicle.

 

All 6BT Cummins motors through 2003 were front gear train (regardless of application; Dodge, generator, bus, etc.). The Common Rail in 2003+ was a rear gear engine.

 

The Dodge 5.9/6.7 remained front gear train and still are.
