260k+ On My second truck both 5.3's, I've replaced every accessory, suspension, steering and brake part in the past 8 months.... but never pulled a valve cover or dropped tranny on it. The truck still drives like new, w/ the exception on the 22's and the slow windows lol

260k on an 01 and runs great. I did just have to put all new injectors (3 failed at same time, maybe bought some bad gas?) and it uses a quart of oil between changes. Put an 06 tranny in around 200k I think.
