You do have quite a few variables here. A 30k motor could burn up just as easily as the motor you have now for any reason including unknown history. So you have that to go with swapping the motor with or without its fuel injection parts or doing the work to swap out the manifold and carb it. You have a 4wd transmission that would need a tail housing swap to go 2wd or keep the transfer case and not run a front driveshaft but might have to make a rear driveshaft work either way due to length issues and crossmember that may or may not need swapped. I personally have no experience with plow trucks but not sure how a 700 would hold up to pushing snow but i know they hate heat but can be built up to do that type of work. If all thats really wrong with your truck now is an overheating issue i would investigate that first. There are a lot of things that could go wrong and other parts to source, having a complete vehicle to get parts from is always a plus and scrapping parting out what you dont need is always a good way to get some money back. Everything could go fine too though there is no telling. Really a question of how much money you could put into it and how much time you can have the truck parked really.
