    I have been told that this truck was made by special order only and that the 5.3l has a 327ci vs the other 325ci 5.3l which is a much better engine. Can anyone verify these claims? Or does anyone know of this package that can offer some insight? She has a superchip, AFE cool air and a few other tid bits as I'm still exploring whats been done, runs like a dream so not complaining either way, just good to know if this is true. Thanks everyone for reading.

    Was it built by a Upfitter? ( A Pkg Co that builds trucks and cars for the dealerships at High Markups)

    I know thats a distinct possibility, although I'm not sure how to tell. I know when the DMV runs it, it shows as a base silverado 1500 LS with 4.7. (wrong engine size)

    If you are talking about the back of the truck then no. a small oval sticker from a local used car/truck dealer but thats it

    I am thinking it's something aftermarket more and more..although no extra decals (other than 13xtreme) to indicate a company. Just got off the phone with the local Chevrolet dealer and they had never heard of it..
