7.3 of that era is pretty good engine. I would put a grant turbo on it. INjectors are easy and cheap to install.
Trans, I rebuilt mine at 115K miles, hard, hard use. Upgraded for some heavy duty extra's, upgraded trans cooler helpful if pulling heavy loads in the heat in Az. I pulled a 4 horse steel trailer with 4 horses, engine is strong.
I had a jake brake installed on mine to help on those 7% down hill grades with the heavy load.
Mine got 15 mpg, 12 pulling 10K lbs.
Glow plugs go out, buy lucas, I may have some extra stuff, send me a pm, new upper and lower radiator hoses, glow plugs, will give you a deal.
