"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.
