1997 12v motor

I found a 1997 12v engine at a junk yard and had to buy it. It has all accessories still on it. Had an auto tranny behind it and 141,000 miles on it. Have no idea about what condition the internals are in. Truck was wrecked somehow and engine was put on a shelf and labeled as a gas motor. Been sitting there for 7 years. The only way I know anything about it is from a tag that is tied to the injection pump.

Asking $3000 complete! I think I can part it out and prob get that.
