    Camel hump heads are OLD technology. Get some vortecs or World heads or somthing similar. I think camel humps barley flow 200 CFM on the intake. They also have poor designed combustion chambers.

    camel back's = high rpm heads
    get a set of vortec heads or aftermaket based on vortecs
    they flow better in the usable rpm range or street
    free 40 hp

    You could go with a sleeper cam, wide LSA with higher durations. If you keep the LSA nice and wide you can run higher durations. It'll take away a little bit of midrange compression but I doubt the emissions will be effected.

    Re: some engine help

    what year of truck are we dealing with here? that will play a major part in what carb you can use.
    77 Chevy K20 - 80 GMC K2500 (in pieces)
    90 Chevy K3500 - 93 Chevy C2500 (in pieces) - 94 Chevy K1500
