Swap in a 7.3 Powerstroke? or a Cummins?

Well first things first, hello everyone, my name is Stefan and I hope to be welcomed. Here is my predicament.
I recently purchased a 7.3L Powerstroke that I had originally planned to rebuild and replace the current 7.3L I have in my 97 F-250. However, my uncle confronted me and wondered if I could put it in his 99 F-350 V-10. I was just wondering if any fellow members have attempted this before or if I should just do a 12V Cummins swap with an Allison.

Thank you, Stefan

I know, that's what he is wanting to get rid of it. His V-10 has 250,000 miles on it and after seeing all of the things my 7.3L has done, he wanted to know which swap would be better and cheaper. The 7.3L or the 12V. I've never been around a 12V or 24V Cummins so it would be all new to me.

By better I mean more bang for his buck. Price for power and fuel economy. It is used strictly as a farm pickup feeding bales to cows. His V-10 is getting anywhere from 5 to 7 MPG because of all the stop and go, and i think a cummins with an allison would make a nice setup for the pickup. The only reason I am weighing my options here is because I already have my extra 7.3 Powerstroke i purchased setting on the shop floor complete. :confused:

you could make the powerstroke work, but the 12 valve cummins would be much easier.

If you want fuel mileage and don't need big power, I recommend a Cummins 3.9 4BT it is a the same as the 5.9 but in a 4 cylinder.

If you use the PS you will need a near complete donor truck wiring harness, and gauge cluster'

with 12 valve cummins 5.9 (or 3.9) you can basically use the V10 harness and gauge sending units, you may need to buy an aftermarket tachometer. Also with the cummins you can almost run any transmission.
