A serious quest I see. Nothing wrong with that. Poses sincere questions.

First. The Cummins having what advantages of an already available Power stroke that's already in there. I've had some wild ideas over the years, but the easy button is always worth a look.

I do have a friend that stuffed a Cummins in a square body Chevy. Tight, not impossible, but a lot of work, for? The Ford, with the latter years of clutter would seem to be that much more complicated. Just wondering.
