I don't know if the 283 was "rare" for that truck, but sixes were much more common. At 35,000 miles, and considering the work it needs, it still seems like something worthwhile, even if that mileage is the second time around on the odometer. I think "worth" in this case is in the eye of the beholder- which includes the seller. If you do the body work (or some of it, or most of it) yourself, it would even be more favorable.
