Crazy diesel combo

Ok guys its my first post here normally I'm on the dentside forum. Anyway I had a crazy idea today at work. I came up with the idea to machine up a diesel radial engine. Yes I know it's a lot of work and time and probably way more money that I would be comfortable spending. So I'm asking if I were to use the same bore and stroke as a 7.3L and had 6 pistons per bank, what kind of horsepower do you think it would have? To keep up with the times it would have forced induction of some kind. Yes I'm crazy when it comes to these ideas but some has to have them.

That is an interesting idea. I have done a lot of work on older gasoline radial engines, but haven't run into a diesel fuel type yet, and not even sure if they exist out there.

I am not sure what horsepower potential you could have, there are too many unknown variables at this point to even guess. I would suggest you start with a small prototype, something that can leverage off-the-shelf components from farm machinery, that would give you a good idea of success and effort. This could save a lot of lathe and milling time.

There are some generators and water pumps used in the past ran by radials on diesel, but they are the size of a semi truck. Yep i was thinking to use off the shelf stuff. Find a 7.3 with at least 6 good rods and pistons, see if I could get a rotary injection pump from a cummins. Then I'm left with everything else. Are the idi's and early powerstrokes sleeved engines? If I could get it built and running it would be cool to put it in a T-bucket or something unique.

The IDI's (indirect injection) engines were not sleeved. The early 7.3 was basically a 6.9 bored 110 thousands which made for very thin cylinder walls.

Far as I know, none of the powerstrokes have sleeves.
