Thanks for the reassurance. As I said, runs great- no smoke, no leaks, no misfires, no bad obd codes, no oil in cooling system, no coolant in oil, no bottom end noise, and it was not the typical "cop" truck. I guess the evidence technician was a little easier on it. Interior was clean, no rips or tears. When I saw the 12K, I almost fell over. I don't know much about the 4.8L. I'm going to be around on the forum now. Great site guys!
