    also if you want our opinions we need to know a little more about it like what you want to do with it? mud and sand rocks? do you want more high end or low end?

    Call and ask one of the Many Cam Company's out there.
    They need to know:

    Engine how many cube's
    Tire size
    Intended use of vehicle
    Automatic or stick, if auto, converter stall
    Idle quality,Preferance's, as in Lumpy Idle, Smooth idle etc.

    Get all of this info if You can, and then call:
    Comp Cam's
    Crane Cam's
    Iskenderian Cam's
    Crower Cam's
    Summit Racing
    PAW
    the list is endless........... /forums/images/graemlins/eek.gif

    Comp Cams 12-249-4 or 12-388-4 (almost identical, but 12-249-4 gets a hair more lift and both recommend upgraded springs: 981 or 983 I believe) are about the only two from Comp that do not require a custom burned chip. Crane Cam's compucam line have a couple of cams that also should work with stock computer, but I found that comp's operating ranges were better than Crane's.

    for now its all mud and nothing else, but were moving to arizona in the next year or two so it its gonna be sand and rock later(gimme the mud any day of the week), my truck has 4.88 gears so its got no top end, so with that in mind id like one for a little lower than mid range if there is such a thing.
    Stats:
    Weight of vehicle: Roughly 4500 pounds
    Gear Ratio: 4.88
    Engine CID: 350 5.7 Gas Engine
    Tire size: 35x12.50
    Intended use of vehicle: 80% DD, 20 in the mud
    Automatic or stick: Auto
    if auto converter stall: Dont know
    Idle quality Preferance's as in Lumpy Idle, Smooth idle: As for lumpy or smooth id have to see how they feel in someone elses truck

    Im running

    CCA-742-16
    001 CCA-981
    001 CCA-CL12-239-3

    This is a Comp Cam extreme energy truck cam. It makes nice power off idle and scream mid to high end. off idle to 6600 rpms is its specs. It has a nice romp to it to. A bit more than I was expecting comparing it to a 262 cam. I have been very pleased.

    Between comp and crane, I noticed that crane has cams better suited to not cause problems with the computer. Very important. The crane 204/214 112* cam should be really good for an FI truck, but ask them.

    Don't think comp has any "low end power" cams that are on a 112* or numerically higher LSA, and LSA is important on FI engines. The lower you go, the more problems (modifications) you will have to do.

    call comp cams. I have dealt with them for several years. I run comp cams in everything! They have more cams than they list in catalogs. and will custom make one for you if you have special needs.
