COMP Cams Camshaft FW XR294Rf-HR10

This COMP Cams Xtreme Energy camshaft is designed for Ford 351 Windsor engines. You're getting the camshaft itself, which is a hydraulic roller type, specifically the XR294RF-HR10 model. This camshaft is intended for builds aiming for street and strip performance, typically requiring a 9.5:1 compression ratio, aftermarket intake, and headers. It's also best paired with a torque converter of 3000 RPM or higher and rear gears of 4.10 or lower to make the most of its aggressive profile.

The Xtreme Energy series is known for its strong performance gains, and this particular grind features 242 degrees of intake duration and 248 degrees of exhaust duration at 0.050 inch lift. This duration, combined with the hydraulic roller design, means you'll see a noticeable bump in power, especially in the upper RPM range. Be aware that this camshaft will result in a rough idle, which is characteristic of performance grinds like this one. It's built for engines that have the 'Old' firing order or the 'Windsor' firing order, making it a versatile option for many 351W builds.

When installing this camshaft, remember it's designed for specific engine setups. It works well with engines that have an aftermarket intake and headers, and it really shines when matched with a high-stall torque converter and aggressive rear-end gearing. This camshaft is not approved by the California Air Resources Board (CARB) and cannot be shipped to California. Always consult the manufacturer's installation instructions for proper setup and break-in procedures.
