4.8, but I just passed 200,000 miles, and no engine or transmission trouble until a couple weeks ago. The engine did not use a drop of oil between oil changes (every 3,000 miles). NOW, however, I have all of a sudden smoke pouring out of the tail pipe at start up, and oil consumption like crazy.
I fixed the PCV smoke issue, no oil consumption now.
I did my first brake pad change after 250,000.
I did my first spark plug change at 240,000. I still haven't changed the wires.

Just bought my wife a 04 Tahoe Z71 that just clicked over 222,222k miles. Bought it from the 2nd owners who had it since 70k. Only things that were done by them were a water pump, rotors/pads, tires, oil changes. Original motor and tranny and tranny fluid has never been changed 
But I got it cheap enough I can put a tranny in it if it goes out. As soon as I got it I did plugs, wires, fuel filter, cold air intake, tune. I also did a power steering pump but it didnt fix the problem. Looks like im gonna have to put a steering box on it. I did a steering shaft also. About the level the front end and put new shocks too.
