I'm considering the purchase of a 95 cummins dually, 2wd standard cab to transform into a much faster diesel than what I have already.. I've heard of how the 12 valve is a great motor, though I honestly know very little about the cummins.. I want to run atleast 13's on motor.. If anyone could give me some advice on products and pricing, I would be very appreciative.. By the way, I believe I can get the truck for $5500.. The truck has a good body, decent interior, and cold ac.. It has 192,000 miles on it.. Would this be a decent deal?? I looked at it yesterday, and need to make the deal soon if I'm going to.. Thanks..
