COMP Cams Camshaft CBVI XR294HR-14

This is the COMP Cams XR294HR-14 Xtreme Energy hydraulic roller camshaft, designed for Chevrolet Big Block GEN VI engines. It features a 242-degree intake duration and 248-degree exhaust duration with a 114-degree lobe separation angle, making it a strong choice for builds looking for improved performance, especially when paired with nitrous or blower applications. This camshaft is intended for serious engine builds and requires supporting modifications to perform optimally.

To get the most out of this camshaft, you'll need a torque converter with at least a 3000 RPM stall speed, along with other upgraded engine components. The hydraulic roller design means it's built for durability and reduced friction compared to flat tappet cams, allowing for more aggressive profiles and better valvetrain stability. Its specific lobe profile is tuned to work well with forced induction or nitrous, providing a noticeable boost in power when those systems are engaged. This camshaft fits a range of Chevrolet and GMC trucks and vans from the mid-to-late 90s, including models like the C2500 Suburban, K2500, and Express 3500.

When installing this camshaft, ensure your entire valvetrain is up to the task. This includes checking your valve springs, pushrods, and lifters to make sure they are compatible with the camshaft's specifications and the intended use. Because this is a performance camshaft for specific applications, it's crucial to consult with your engine builder or refer to COMP Cams' detailed installation instructions to ensure proper setup and to maximize its potential while protecting your engine.
