Here's the story - my neighbor has a 1993 f-350 dually with a flatbed that dumps... only problem is that the engine head is cracked. He just GAVE me the truck, so no money lost if the truck isn't salvageable.. It's only got 145,000 miles on it, but anyway, he says the truck will only run 40 miles before it gets overheated, and it also smokes pretty bad... I'm sure I'm forgetting something too... So to my question... Is the truck worth the time and money to fix or should I just pass?
