COMP Cams Camshaft LS1 289Lrr HR-114

If you're building a high-RPM, race-only LS engine with aftermarket rectangular port cylinder heads and higher compression, this COMP Cams camshaft is designed to give you that broad top-end power you're looking for. It's a hydraulic roller grind specifically tuned for these demanding setups, aiming to maximize performance when the engine is really singing.

This camshaft, part number 54-471-11, is part of COMP Cams' LSR Rectangular Port series. It features a 239/255 degree intake/exhaust duration at .050 lift and a 114-degree lobe separation angle, which is optimized for delivering strong power in the upper RPM range. It's built for LS Gen III and IV engines, and while it fits a wide variety of vehicles like the Chevrolet Camaro, Corvette, and Silverado, its intended use is for dedicated race applications where maximum top-end pull is the priority. Remember, this camshaft is not CARB approved and cannot be shipped to California.

For serious LS engine builds focused on peak performance at high RPMs, this camshaft offers a well-built option. It's important to ensure your cylinder heads and compression ratio are matched to this grind for the best results. Always consult the manufacturer's installation instructions for proper setup and break-in procedures.
