    Damn!!! That's sweet... Hell, if I saw that, I'd saved my dinero, and passed on the 5.3/4L60E.

    I got my 00' 5.3L 4l60E for $500 bucks. LS1 heads $150 and 03' Z06 cam, springs and push rods for $250.
    Good deals are out there on 5.3L if you can find them.

    Go 6.0L if you have the funds.
    SOON TO COME!!!!

    I didn't see a check box for a 720 HP 572 GM crate engine. Otherwise I have to chose the LS2 for the 6.0L and 400hp fresh out of the box and light weight. They say 100 lbs of weight reduction is good for .1 seconds in the 1/4 mile so that works for me. Now all I need is to get a little bitty gal to drive my truck to make it .1 seconds faster than my times. It works with Danika Patrick.

    if price is an assue, the 5.3 swap kits are cheep due to the fact everybody wants a 6.0.......
    get a 5.3
    swap in a big cam
    mill down the heads
    get shorter pushrods
    get some 4.88 gears
    go have some fun...(now that you have spent more money than a 6.0 would have costed)
