Anything can be done it all depends on how fat you wallet is you would have to have a good shop to work in and have access to a welder and cutting torches. Finding a good used engine is another big task you can look at paying 4000 for a complete engine and finding a NV4500 transmission. Probably the easiest thing todo is find a junked Dodge with a good engine and buy the whole truck and go from there. You will have to gut the interior of your truck and insulate it for sound deadening a Cummins in a 79 would be pretty loud you would need to wear ear plugs.

Good luck on the project

I like both motors, and have used both in the past to pull some heavy loads ,10 tons plus. The mechanical end can be fixed, with engine mounts etc, but the electrical end is my concern. How much more wiring is going to be involved, and headaches, cummins versus powerstroke? Itll be a manual trans config, either way.
