    Performance Cam info is best answered by the pro's.

    Try Crane Cams, Edelbrock, Comp Cams, etc.

    Hopefully you are already letting the Motor breath better with a CAI and Headers.

    If not, best to start there, then do a cam.

    A new Chip Tune will definitely be in order.
    Pavement sucks... :grrrrrr:

    I'd call CompCams at 1-800-999-0853, they have some nice truck cams for street and track. Edelbrocks says there LS type cams are not for trucks. Crane Cams shut down last year and was purchased by S&S and is reorganizing.
