Just some heads-up:

On that first one: nicely equipped, but Ford did not have a turbo-diesel in 1991, let alone the later Powerstroke version. Unless someone put an aftermarket turbo kit on it (and that engine takes to those very well) it's probably a 185hp/360tq non-turbo 7.3L, not suitable for pulling much more than an open trailer.

On the second one: Ford did not install the Powerstroke in the E-chassis until 1996, thus it's likely a non-Powerstroke turbocharged Navistar 7.3L, with 190/395 hp/tq ('96 PS was 215/425). Still a good engine, and responds well to mods, easily increased to better-than-PS power levels. Personally, I think it's a plus to have the good ole tried-and-true mechanical injection pump without all the Powerstroke electronics... - GA
