If you don't go with Chase (which I recommend, he know's his stuff), then I got a guy in Clayton that can do it, he is a heavy equipment mechanic by trade but he has a consistant side business of fixing trucks/tractors at his house, he's actually doin a 6.0 for a guy right now, recently did a 5.3 and a 6.5 deisel, but he def knows his stuff when it comes to engines, axles, trannys, pretty much whatever.
