what does everyone think of these, gas mileage in my 71' fj40 is killing me, so i want a diesel and i have a chance to get a k20 stepside with a 6.2 diesel in it for relatively cheap, im not looking for a speed demon diesel or anything, just something that gets alright gas mileage....SO, what does everyone think of these motors.

they are by no means a power house at all but they get 25-30mpg no matter how hard to drive them. if its in good running cond. they are pretty good. some problem's they are known for are head gaskets blowing, injection pump failure. but for the most part they are good as long as somone hasn't tryed ot get more power out of them (the bottoms can't take it). if its a good deal go for it, cant beat a chevy :D

yeah you put free flowing exhaust on it and you will get a bit better sound, changing it to an electric fan will help it out as well as far as gaining a few hp's and mpg's.;)
