Does the engine turn over? If it does, I would backflush the cooling system by replacing the thermostat with a piece of thin cardboard and connecting a hose to the heater hose fitting. Let the water run out the water pump hole, and do not open the block drain until the junk is out. Put it back together and stick it in the truck. With fresh oil, prime the oil pump like a new engine and let her rip. You might have to reseat the rings, but you probably will have a good engine.
