    4.8/5.3/6.0 all come with same injectors

    275/285/325/345 hp motors all with stock injectors....think about that
    2002 Lightning - GT headed 5.5Litre w/ Twin 7665s
    2002 Silverado - 427Lsx w/ Twin gt4202s
    2010 Silverado crewcab Z71 - 5.3litre w/ procharger
    2000 Wrangler - 5.3litre with some stance
    2014 Xsport- 3.5 Eco boost
    412 Motorsports

    it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference

    What about the size of the 5.3 flex fuel injectors? They have to flow about 30% more than the regular ones just to get the engine to run properly on E85.

    I have never seen a flow number for the size of them though to make a comparison.

    if it's a 6.0 vette then it has an LS2 in it which means it will have 36lb injectors which would be a good upgrade for you...now if its the LS6 5.7 vette then i wouldnt waste the time on them
