    Question Which cam is better?


    Im a big fan of crane cams and am looking to upgrade from my crane energizer cam to either a powermax or z cam. Which one will get better torque? I understand powermax has longer exhaust duration for better exhaust flow but z cams have accelerated valve action. I want almost the same specs i have which are .470 lift and 222 duration @ .05 Any suggestions on which one would be a better upgrade? HP is great but im leanin more toward better torque! Thanks !!

    The accelerated valve action cam will give you the most torque. Roller cams are even better yet for torque.

    "SuperNOVA", the Zcams are a direct result of a Comp Cams
    design ,the Xtreme Energy line. Faster ramps e.t.c. Lobe design
    was designed to resemble as close as possible to roller designs,
    in a flat tappet hyd. grind.They produce a combo of best of both
    worlds.Also, tend to make the motor think has more static comp.
    'cause of lobe separation.these type of grinds still have good bottom end, and still make more top end than older single pattern
    cams w/similar duration.Try It, You won't be sorry.
