I have a 98 sohc 3.5 sitting here, it was overheated. That is all I know about its past. It runs fine at the moment. I have put 100 miles on it out in the desert. The truck it is in has a salvage title and a bent frame. If I had a rig and needed an engine I would drop this one in and see what happens. Yes it will need seals and timing and back maintenance. Just throwing this out as another route.
