COMP Cams Camshaft LS1 XEr287HR-12

When you're looking to get more out of your GM LS engine, especially those with larger displacements like the LS1, LS6, or even custom builds, this COMP Cams XFI Xtreme Energy-R camshaft is a solid option. You'll receive the camshaft itself, ready to be installed into your engine. It's built using COMP Cams' XFI XE-R design, which is specifically tuned for engines in the 5.7L to 7.0L range, including popular applications like the Chevrolet Corvette, Camaro, Silverado, and Cadillac Escalade.

This camshaft features a hydraulic roller design, meaning it uses roller lifters to reduce friction and wear compared to flat tappet designs. The grind specifications, 238 degrees of intake duration and 240 degrees of exhaust duration at .050 inch lift, are chosen to provide a noticeable improvement in power and torque, particularly in the mid-to-upper RPM range. This type of camshaft is often chosen for builds where the owner wants a more aggressive engine note and a significant bump in performance without going to an extreme setup. It's designed to work well with LS engines that have upgraded cylinder heads and intake manifolds, making it a popular choice for performance-oriented LS swaps and rebuilds.

Keep in mind that this camshaft is intended for performance applications and is not CARB approved, so it cannot be shipped to California. For optimal performance and reliability, it's always recommended to consult the manufacturer's installation instructions and ensure you have the correct supporting components, such as valve springs and pushrods, that are compatible with this camshaft's specifications.
