    I drove a suburban with a 5.3 and that thing screamed! Peeled out from a stop and was more than fast enough for me. I guess the 5.3 winds up quicker than the 6.0?

    My 5.3 runs ok in my tahoe...nothing to write home about at all. Wide open throttle and part throttle leave a bit to be desired in my tastes. But then again, I think everything I drive could use more power. I Would definitely love to put a supercharger on mine, but the "miracle transmission" would probably run out of magic dust if that were to happen.

    I got to thinking about this after I posted a few minutes ago. This would pretty much be my breakdown of how to get the most out of your 6.0L without hurting mileage substantially. This is what I would do to my 5.3 anyway...same thing I would do to grayson's burb.

    K&N Filtercharger
    Exhaust, probably Magnaflow because for the money, its a pretty good system
    2005-UP GM Electric Cooling fans with adapter harness
    1.85 ratio rocker arms and new valvesprings
    programmer

    I've never done it. I've thought about it, but everytime I see a set of the 05 and up fans come up for sale for a decent price, they sell before I get to them. From what I can tell, the fans are a direct bolt on if your truck comes with the 34" wide radiator, and nelson makes a factory style wiring harness to tie them in with. From there it's a matter of getting the fan controls enabled in the computer which on 03-up isn't a big deal. On 02's I don't think it is either, but I haven't verified that yet. Seems like a pretty painless process other than the cash to do it.

    Well, if it's like the OBDI or OBDII LT1 ecm's, it's a matter of turning the controls on or off in the programming and setting the temperatures. Knowing GM, it's probably still this way. I don't know, I've never messed with any of the LS motor ecms. Flem might know, but I could probably find out from a couple people if I was really serious about doing it. I guess I need to look into it again because I don't really see anything but positives to putting the factory fans on.
