COMP Cams Camshaft LS1 293Lrr HR-114

This is the COMP Cams 54-472-11, a hydraulic roller camshaft specifically designed for GM LS Gen III and Gen IV engines. It's built to deliver strong top-end power and excellent performance at high RPMs, making it a great choice for race-style LS engines, especially those equipped with aftermarket rectangular port cylinder heads. This camshaft is compatible with a wide range of vehicles, including popular models like the Chevrolet Camaro, Cadillac CTS, and Chevrolet Silverado, across various displacements from 4.8L to 7.0L.

The LSR (LSR Rectangular Port) designation means this cam is optimized for engines using rectangular port heads, which are common in many performance LS applications. With a 243/259 duration split and HR-114 lobe separation angle, it's tuned for aggressive power delivery. This camshaft is a well-built component for enthusiasts looking to extract maximum performance from their LS engine, particularly in demanding applications where high-RPM breathing is crucial. It's designed to work with hydraulic roller valvetrains, offering the benefits of reduced friction and improved durability over older flat-tappet designs.

When installing this camshaft, it's important to ensure your engine setup is appropriate for its aggressive profile. This includes having compatible cylinder heads and potentially upgraded valvetrain components like stronger valve springs and pushrods to handle the increased lift and duration. Always refer to the manufacturer's installation instructions for specific details and recommendations to ensure optimal performance and longevity.
