I would love to do a 73-79 F150 shortbed 4x4 with a 4bt. Keep the stock np435, np205, D44 front, and 9" rear. Keep the gearing the stock 3.54s and bolt on some 37s under no-lift with lots of artful trimming. The gearing would be pretty dang good for the diesel then, even without the overdrive.
94-98 P-pump engines are my favorite....the 91.5-93 rotary pump engines are just as good under 300hp.
You are the guy to do the F150 swap 'n trim!
As far as engine choice, I think you are bang on with any p-pumped 12 valve being the best 5.9. I also agree on the reg cab long box power wagon, as my 3 kids come with 12 paws, and thus can ride in the camper!
