    or buy a 5.3 and turbo it! then build the lil 4.8 bored to a 5.7 forged and you'll be turboed already and have enough motor to upgrade to L92 heads

    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

    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

    You can hide a lot of things with the stock muffler. I'll go take a video of my truck with the stock muffler and with my cutout open.

    for ballpark im hoping to spend around 3 grand for everything. and thats me doing all the labor myself. i found a lq9 with 80e with 85k for 1200 on craigslist one time and i wanted to get it but sadly i didnt have the money. and it will be going into 99-02 scsb. and if i cant find an lq9 at a decent price then i will get an lq4. but so far i think ill be going with cai, lt's, ls6 heads and cam, h-pipe, and maybe a locker.
