The likelihood of you ever seeing this comment is astronomical, but anyways, I do indeed have a 2000 Z71 Silverado with 489,867 miles on it, and there is nothing wrong; it still runs just as good as it did when I purchased it off the showroom floor.
Now with that said, it is the original engine, no rebuild and no major components have been replaced, with the exception of O2 sensors; you know, things that must be replaced.
The fuel mileage is great with this, but I am at a low elevation, thus giving me more MPG; otherwise, being at a high altitude will give the user less MPG, for the simple fact that it is naturally aspirated.

I just came across this survey and had to read all of the comments. I own a 2000 Silverado LS with the 5.3 mtr. I got a smile on my face when I read the comment posted on 1 Aug.2002.
My Silverado has 392,000 miles on it and has never had engine problems. I still drive this truck everyday; headed for the 500,000 mark.
