    Why are these Comp Cams full roller rockers the same price as the stamped steel roller tipped ones? Will they break?

    I am looking for a something to use in a street motor with .566 inch lift cam.

    They look like the old Cam Dynamics cast aluminum rockers...Work great on non-roller cams

    .

    You have to be careful with cast stuff and high loads.
    I've used them in the past, because that's what they had back then,
    but a forged or billet piece will be stronger.

    You spent the dough for a roller cam lifters and springs, good heads and internals to make use of the roller cam and you want to skrimp the last $100 by not b]getting the PRO-Magnum Comp steel roller rockers?


    Might as well use a stock 12" converter and 2.41 single track gears and 225r 78x14 tires.

    Get real rockers, no need to chance the cast stuff on a HP vehicle.

    The high energy series rockers matches the High energy cams.

    Don't be afraid of Harland Sharp roller rockers...They are the best, IMO, and are a shade over $200

    Point taken.
    I did see some Harland Sharps for 250 but wondered if that was just another bottom of the line part with a good name on it.

    The extruded aluminum rockers like Harland Sharp are much better than die cast.
