COMP Cams Camshaft LS1 289Lr HR-114

If you're building a high-RPM, race-only LS engine and looking to maximize top-end power, this COMP Cams camshaft is designed for that specific goal. It's built for use with aftermarket cathedral port cylinder heads and higher compression setups, aiming to give you that broad powerband needed for serious performance at the track.

This camshaft features a 239-degree intake duration and 247-degree exhaust duration at .050 lift, with a 114-degree lobe separation angle. These specs are tuned to deliver strong performance in the upper RPM range, making it a solid choice for LS1, LS2, LS3, LS6, and other Gen III/IV V8 engines found in a wide variety of vehicles. For example, you'll find this cam suitable for performance builds in models like the Chevrolet Camaro, Cadillac CTS, and Chevrolet Corvette, among many others. It's important to note that this camshaft is intended for race-only applications and is not CARB approved, meaning it cannot be shipped to California.

When installing this camshaft, ensure you have the necessary supporting modifications, such as upgraded valve springs, pushrods, and potentially a new timing set, to match the camshaft's specifications. Proper setup is key to unlocking its full potential and ensuring reliable operation in your performance engine build.
