COMP Cams Camshaft LS1 305Lrr HR-115

COMP Cams has a solid reputation for making performance valvetrain parts that help engines breathe better and make more power. This particular camshaft, the 54-475-11, is a hydraulic roller grind specifically designed for GM LS GEN III and GEN IV engines. It's built for applications with 440 cubic inches or larger, focusing on making serious power in the upper RPM range, specifically above 6000 RPM, and works best with rectangular port cylinder heads.

This camshaft features a 255/271 duration rating and a 115-degree lobe separation angle, which is a popular setup for maximizing high-RPM performance in LS engines. It's designed to fit a wide range of LS variants, including the 4.8L, 5.3L, 5.7L, 6.0L, 6.2L, and even 7.0L displacements. You'll find it suitable for popular vehicles like the Chevrolet Camaro, Corvette, and Silverado trucks, as well as Cadillac Escalade models, among many others. Keep in mind that this camshaft is not CARB approved and cannot be shipped to California.

When installing a camshaft like this, it's important to have the right supporting components. You'll want to ensure your valve springs, pushrods, and potentially your timing set are up to the task to handle the increased lift and duration. This camshaft is a great choice if you're building a performance LS engine where high-RPM power is the main goal.
