It doesn't sound like you're all that enamored with the truck. You need to keep in mind that other things can and will go wrong with these even after the expensive motor replacement. That's something to factor in to the equation.Right - in all seriousness, is it actually worth fitting a second-hand engine? Is there anyone particularly good for getting an engine from? I've spotted a couple of sellers with 90-100k engines on eBay around the 500 quid mark, with about 60 quid to ship. They don't offer much of a guarantee though.
