    Absolutely nothing, the only difference is one is more expensive than the other, and a different emblem. GMC's tend to be more like fancy Chevy's, but since they make all the trucks like Cadillac's now, GMC is kinda useless now.

    They even come off of the same assembly line. (or at least some did)
    I've seen a local truck here(a few years ago now), brand new on the sales lot, chevy silverado logo's and stuff on the outside and a GMC sierra trimmed interior.
    Word on the street years ago was that Chevy was the "poor mans" GMC.

    gmc was considered by gm as their higher end line before they started with the caddillac.
    from what i understand, years ago the gmc even had galvanized sheetmetal where the chevy line did not and always had just a little more luxury to them

    the code was only the engine generation model for a year period, it had nothing to do with the make like the lly was used in both chevy and gmc in the same time period same with the lbz and lb7, some years there was overlap like 07 where you could get the new engine in the old body style or you could still get the previous generation engine too

    I think the difference between a GMC and a Chevy is purely cosmetic.
