COMP Cams CL42-423-11 Xtreme Energy Hydraulic Roller Cam Lifter Kit for Oldsmobile - 224/230 260-455

The COMP Cams CL42-423-11 Xtreme Energy Hydraulic Roller Camshaft and Lifter Kit is engineered for Oldsmobile 260-455 cubic inch engines, delivering a noticeable improvement in throttle response, mid-range torque, and top-end power over a stock camshaft. The Xtreme Energy series is designed to offer maximum performance gains while remaining streetable, making this kit ideal for performance street builds, muscle car restorations, and weekend cruisers that demand more power without sacrificing drivability.

The hydraulic roller design reduces valvetrain friction compared to flat-tappet camshafts, resulting in improved efficiency, lower heat generation, and extended component life. COMP Cams' Xtreme Energy grind (224/230) refers to the advertised duration at 0.050" lift, providing a well-rounded power band with strong vacuum for street use.
