    best cam for 03 5.3 liter.....

    sorry did a search and for some reason it wasnt working.

    I have a 5.3 short wide reg cab...Only mods are throttle body bypass and efi live...I have modded the stock air box and it has a flowmaster muff.

    Nitrous, headers and converter are in the works.

    What would be the best cam, and the best deal? Thanks!

    I wouldn't go too crazy with the cam yet since you don't have the supporting mods--but will. How big of a converter are you going with? 2WD or 4WD? Gears?
