very possible, depending on gears and locker unit it came out with and weather. Most 05s came with g80 and 3.73s. One of my friends ran a 14.8 on his bone stock 07classic 5.3 chevy with about 200 miles on it.

I just came back from the track and my bone stock '03 RC step side with 44K miles ran a best of 15.5 at the CA speedway. When I say stock I mean stock down to the paper air filter element. The elevation at that track is about 1100ft and I was told today's DA was +3300 or something like that. We had very bad air because of some large fires in the area that was raining down ashes all day.
