COMP Cams Camshaft CS 47S XE294H-10

This COMP Cams Xtreme Energy camshaft is built with a 250/256 degree intake/exhaust duration and a 110-degree lobe separation angle. It's designed for Chevrolet Small Block engines from 1958 through 2002, covering displacements from 262 to 400 cubic inches. This camshaft is a solid option for Pro Street and bracket racing applications, but it will require supporting modifications like a good intake manifold, headers, and a torque converter with a stall speed of 3300 RPM or higher to really shine. It utilizes a 4/7 swap firing order, which can help improve exhaust scavenging and overall engine balance.

The XE294H-10 is a hydraulic flat tappet camshaft, meaning it uses traditional flat tappet lifters. If your engine was originally equipped with roller lifters from the factory (common in many 1987 and newer GM cars and trucks), you'll need to confirm your block's provisions. COMP Cams offers specific hydraulic roller lifter kits for various block years if you wish to go that route, or you can stick with a hydraulic flat tappet setup if your block is compatible. This camshaft is well-suited for builders looking to extract more power from their classic Chevy V8, especially those focused on drag strip performance.

When installing this camshaft, it's crucial to follow the manufacturer's recommended break-in procedure to ensure proper lifter and cam lobe seating. This helps prevent premature wear and ensures the longevity of your new valvetrain components. Always refer to the COMP Cams installation instructions for the most accurate guidance.
