The Xtreme Energy cam profile delivers strong mid-range torque and excellent top-end power, making it ideal for street/strip applications, hot rods, and muscle cars. This cam works well with aftermarket cylinder heads, performance intake manifolds, and headers. Recommended RPM range is 1,500-6,000 with a power band from 2,000-6,000 RPM. Best suited for vehicles with 9.0:1 to 10.5:1 compression ratio and upgraded valve train components.

COMP Cams hydraulic roller designs eliminate the need for break-in procedures required by flat tappet camshafts while providing superior performance and longevity. This kit represents an excellent value for engine builders and enthusiasts looking for a proven performance upgrade with all necessary components included.
