I am seriously thinking about swapping a 7.3 engine for a Cummins. Here is the details of the truck I am going to buy:

1999-2002 Ford F350
7.3 Engine
4x4
Regular or Crew Cab(Depends on price)
Manual Transmission

Here is my question that I am really pondering. What Cummins engine should I buy? A Dodge Cummins or Cummins industrial? I want to least have a comparable 325 hp; 600+ lbs of torque. I read on the Ford Cummins conversion website not to buy the industrial Cummins due to certain reasons. Is this true or just a way to get you to buy their parts?

If anyone has done one of these conversions, please chime in and help me get this ball rolling. Thanks!

Industrial engines, at least mechanically injected ones are generally set up as stationary RPM engines, they can be interesting to try and drive.

Not to mention you can usually buy a Dodge version cheaper ( many more out there for sale )

If I were to do one, and didn't live in an emissions test area, it would be a 94-98 12 Valve all the way.

You wouldn't buy anything other than the conversion parts from the conversion vendor anyway........

You make some great points Pat. I agree the industrial engine availability volumes are not as high as the Dodge Cummins. Thanks for the input.

Anyway, I am picking up a 1999 Ford F350 4x4 automatic crew cab Tueday. If everything checks out then the search for a 5.9 24v engine, manual trans, and parts to piece it together will begin. I just need to find a reputable used engine house who can provide me with a compression test so I know the motor has good compression before buying. If they won't, on to the next seller. Thought I would include the compression test for anyone else who is planning on buying a used motor.

Just out of curiosity, what specifically interests you in a 24V swap?

Also, you could probably do just as well buying a whole 24V truck running, but ugly. Ranch truck, etc....... then you have all the associated pieces.

For grins, when you get ready to source your clutch pedal, let me know, I bought one for my stillborn 99 F250 swap, brand new in the box from Ford.....

I have dont the swap once in a 04 f350 and will be doing it again in another 04. go with the dodge motor. make sure the spline count on you transfer case is the same as the fords or you will have to do some swapping around. I ran the zf6 in the last truck and will be keep the torque flight auto in this one. you will have to do a little tweaking to get the 24v to your hp requirements. I also recomend using a cr exhaust manifold since it allows the turbo to fit a lot easier.

Swapping a 7.3 for a Cummins in a 1999-2002 Ford F350 is a solid project. For the engine, I'd recommend going with a Dodge Cummins rather than an industrial one. The Dodge versions are more common and easier to find, plus they tend to be cheaper. A 94-98 12V Cummins is highly recommended for its simplicity and reliability, but a 24V can also work well if that's what you prefer.

It's great that you're picking up a 1999 F350. Just make sure to get a reputable used engine house to provide a compression test to ensure the engine is in good condition. If you're sourcing a manual transmission, make sure the spline count matches your transfer case to avoid extra complications.

Good luck with your conversion, and don't hesitate to reach out for more tips or advice!

Given the ongoing issues and the cost of repairs, have you considered upgrading to an F-450 XLT? It might be a more reliable option, especially for heavy-duty needs. The F-450 comes with enhanced features and durability that could prevent similar problems in the future.
