COMP Cams Camshaft CS 47S XE284H-10

This COMP Cams XE284H-10 camshaft is designed for Chevrolet Small Block engines from 1958 through 2002, covering a wide range of displacements from 262 to 400 cubic inches. It's built for street and strip applications, aiming to give your engine a more aggressive feel and sound. Because it's a hydraulic flat tappet design, it works with the original style lifters found in many of these classic engines.

The XE284H-10 features a 4/7 swap firing order, which can help improve exhaust scavenging and overall engine balance, especially in performance builds. You'll notice a rougher idle with this cam, which is typical for performance grinds like this, and it's recommended for use with a 2800+ RPM stall torque converter, headers, and appropriate gearing to make the most of its capabilities. This camshaft is a well-built component for those looking to upgrade their engine's performance beyond stock specifications.

When installing this camshaft, it's important to confirm your engine's original setup. While many engines from 1987 and newer were gradually equipped with roller lifters, this camshaft is intended for blocks that originally used flat tappet lifters. If your block has provisions for roller lifters and you wish to use them, COMP Cams offers specific hydraulic roller lifter kits for various block years. Always refer to the manufacturer's installation instructions for proper break-in procedures and compatibility checks.
