either would work, I have a 93 F350 with a nonturbo powerstroke. The motor has been ok but as expected underpowered. The rest of the truck however has held up pretty well. Over 300,000 miles on the truck, with a motor overhaul at 189,000. It is feeding truck with no significant pulling needed. I am going to have to replace it one of these days and not sure that I need the added expense of a diesel.
