The COMP Cams XE268H-1 Nitrided Xtreme Energy camshaft is a hydraulic flat-tappet profile for Chevy big block 396–454 engines, finished with a nitrided surface for added wear resistance. Built for street machines, it yields stronger mid-range power with a slightly rough idle. A stock torque converter will work, though it performs best with an 1800+ rpm stall converter.
