    vortec and vortec max
    1st off what does the max mean??
    what are the diffrences betwen the 2 and what are the horsepower diffrences
    and is this max package something i can upgrade my 5.3 vortec to?

    also does the max get better/worse mileage?
    thanks ryan

    Vortec is the V6, and the 4.8 & 5.3 liter V8s.
    Vortec MAX is the 6.0 liter V8 engine.

    Vortec can be any range of GM engines, it has to do with the way the intake sends the air into the engine, the vortec max is the 6.0L and has multiple displacement, either 4 or 8, i have an 07 chev crew cab with the vortec max and i get alright mileage in the city and as long as im not flooring it on the highway i get better mileage then my dads truck with a 5.3 in it. hopefully this answers your questions somewhat, have a good one.
