Engine Swap

I do not know what is involved electronically - the E4OD does require a TCM, which I think is integrated with your PCM. It looks like the diesel has a standalone TCM. I see all kinds of adapters for a Cummins to a E4OD, they aren't cheap. So a cummins swap would probably be way easier?

Not necessarily, but they are fairly common and there's a lot of info out there on it. A 7.3 and transmission swap would probably be relatively easy.

Hmmmm...now I am torn as to what to do. I have been reading that doing a 7.3 swap would be a pain in the ass

[glc]

Not impossible though, because the 7.3 was an option in your truck. That means that parts to physically install it shouldn't be difficult to find.

You are right. I have been reading conflicting stores, some say it's hell, some say it cant happen and some say it's easy. I was hoping to be able to use my current transmission and transfer case as I just dumped all this cash into having them rebuilt.

The transmission is a no-go. Read this thread: https://www.powerstrokenation.com/fo...fit-7-3-a.html
