    hey man welcome to the site!
    Is your truck a manual or auto, 2 wheel drive or 4 wheel drive, and what size engine do you have in it?
    these questions will help us help you!

    I'd build it for strong mid range.
    5.3 heads with alittle port work, and maybe even biger valves (the smaller runners will have higher port velocity).
    Look at around a 220/224 or even a 224/228 split duration cam with between .570"-.600" lift on a 113 lobe separation.
    Shift kit
    big tranny cooler (15,000gvw rating or larger) that can be bought in the towing section of your local autoparts (tranny cooler is manditory)
    3,200-3,500 rpm stall

    This list should make you very happy and still get you decent fuel mileage if you can stay off the gogo pedal

    Texas Speed has some great products and TEA does great head porting.

    You can't go wrong with AFR heads, and a EPS (224/230 111lsa or 222/226 113lsa) cam.

    Sell the Z06 cam, and get a larger duration cam. It doesn't have to be a large cam, just one with more duration like a 216/220 114lsa and up to a 228/228 112lsa.

Help?

    Any cam in the range I listed is by know means a Donkey cam, and would be very street able and would provide noticeable gains over the Z06 cam.
    IMO, you're going to need better flowing heads, and a Electric WP, to try and meet you goals with the Z06 cam.
    FYI, you will get better top-end power with the Z06 cam over the factory Z28 cam, but my point is that you can easily do better, and remain very streetable going with a larger (than Z06) cam.

    Good luck with your goals.

    I agree with Blue28, the z06 cam would work, but I don't think it would be worth the effort to install for the small gains.
    I 1st went with a 220/224 .580 lift 112lsa...with in a week I wished I had gone gone bigger and finally after alittle over 6 months I had a bigger cam in it.

    You won't get 400+hp cam only with the Z06 cam.

    You already have pretty decent heads in the 317's The most cost effective thing to do IMO is to get them ported and milled a bit and set up with with some nice PAC beehives like the 1218's or even 1518's if you want a better spring and are willing to spend a little more $$$.

    Since it is a truck I wouldn't go to big on the cam or it will be dog down low. You need bottom end in a heavy truck to get you going. You also have not said if you are going to run a convertor. There are torque cams out there for trucks and that is what I would look at. Really the BEST thing for you is to get hold of Geoff at Engine Power Systems (EPS) and have him spec you one.....

    Oh and the FIRST thing you need before any internal work is headers. Don't forget a tune either......
