I hope to have this burb for many many more years. My youngest of 4 kids is 1 so it has to. The engines seem to be bullet proof from 99-06. I had a 2000 5.3 burb and just abused the **** out of that thing and nothing ever broke and had over 250k on it. Then I started researching the 8.1 and found out it was a marine grade engine and i was sold. I bought this 8.1 with 175k on the clock but I trust this engine. It does not scare me at all as it runs like a top. I'll just have to watch the 4L80E and the T-case.
