My 09 was the same way (5.3). I wouldn't worry to much about it cause mine takes a little over 5 quarts to top off so just being 1/2 - 3/4 quart over isn't alot.

I was worried ar first as well but then I read up on it and alot of guys that run their LSx hard put an extra quart in anyway for protection. Supposedly there is alot of room in the bottom end of these that a little overfill like that should't hurt.

I've got almost 25k on mine right now without a single issue. Just keep an eye on it and enjoy your new truck. Plus you do have the 100k powertrain warranty. Nice color choice btw.
