    10 over your ls1 and use a 4" crank with correct pistons


    4.8/5.3 is same setup. take to 3.9 bore and use 4" crank
    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

    I can pretty much fab anything so I'm not worried bout Anything, I'm just at a learning curve on the new tech stuff.lol My brain needs an upload with this LS stuff. I also have a 55 Chevy Sedan that has a 454 thats fuel injected, but I always wanted an LS1 in that baby. So I will cut my teeth on the 5.3 and maybe the Sedan will get that LS1 after all. I love the way that engine looks.

    Also does any GM drive by wire pedal work or do I have to look for a certain year? Thats the only think I did not get with the engine
