A good saw to play with.....highly underrated saw even comparing to newer saws. I bet it will have some pretty good gains, especially in the chain speed department. Just for the fun of it I put a new crank in a 3700 and they are pretty straight forward and simple to work on comparing to the newer EPA saws. If someone can handle the weight alright one of those will cut your annual firewood needs. They are still one of my favorites, but you have to get them cheap.
