Product Details

This COMP Cams camshaft is a hydraulic roller type, specifically designed for GM LS Gen III and Gen IV engines. What you get in this package is the camshaft itself, ready to be installed into your engine. It's built for engines ranging from 4.8L up to 7.0L, including popular displacements like 5.3L, 5.7L, 6.0L, and 6.2L, and covers various LS designations such as LS1, LS2, LS3, LS4, LS6, and LS7. This camshaft is a popular choice for those looking to get more out of their LS-powered vehicles, whether it's a performance car like a Corvette or Camaro, or a truck or SUV.

The design of this camshaft, with its 227 intake and 243 exhaust duration at .050 lift, is optimized for rectangular port cylinder heads, which are common on many high-performance LS applications. This means it's engineered to work well with the airflow characteristics of those specific heads, helping to increase horsepower and torque. As a hydraulic roller camshaft, it offers improved performance and durability over older flat-tappet designs, requiring less maintenance and providing a more consistent valve train operation. It's a solid option for rebuilding or upgrading the top end of your LS engine.

When installing a camshaft like this, it's important to ensure you have all the necessary supporting components. This often includes new valve springs, retainers, and possibly pushrods, depending on your existing setup and the camshaft's specifications. Always refer to the manufacturer's installation instructions for the most accurate guidance on proper fitment and any additional parts you might need to complete the job safely and effectively.
