    Bob, any set of equal length, long tube headers from a well known manufacturer will be good as long as the primary tube diameter is not over 1 5/8" inch (1 1/2" inch would be even better for the 4.8L
    Picking a cam is almost as easy. You are going to want one than develops torque in the lower RPM range since you will be towing your hot rod & trailer. Weigh the car & trailer & call a few of the cam manufacturers & go with the grind that they recommend. Edelbrock, & Crane do a lot of R & D on "towing" cams (as well as all other applications) so I would call them first.

    X2 what stephan said about the long tubes and the cam. Dynatech and AmericanRacingHeaders have very good longtubes. CompCams has a large selection on cams for the 4.8. In the past I used quite a few Crane cams with very good results but thery were purchased last year by S&S after going out of bussiness do to mismanagment so I don't know anything about the company now. Edelbrock doesn't recoomend there cams for trucks with the 4.8,5.3 or 6.0. There cams are designed for lighter vehicles like cars. I would call CompCams toll free tech line.

    Get a cam and headers for a LS7 doesn't matter what brand the key to this upgrade is to be very carefull not to dislodge the LS7 motor thats attached to them and put that in your truck you should feel some extra power
