COMP Cams Camshaft FW XR288Rf-HR10

COMP Cams is well-known for making performance engine components, and this Xtreme Energy camshaft is a prime example of their focus on improving engine output. This is a hydraulic roller camshaft designed for Ford 351 Windsor engines, specifically those with the original "Windsor" firing order. If you're building a street/strip 351W and looking for a noticeable bump in performance, this camshaft is a solid option.

The Xtreme Energy 236/240 designation refers to the camshaft's duration at 0.050 inches of lift: 236 degrees on the intake side and 240 degrees on the exhaust side. This duration, combined with a requirement for 9:1 or higher compression, intake manifold, headers, a 2800+ RPM stall torque converter, and 3.73 or numerically higher rear-end gears, is tuned for strong performance in the mid-to-upper RPM range. Expect a rough idle with this camshaft, which is typical for aggressive street/strip grinds like this one.

This camshaft is intended for modified engines and is not CARB approved, meaning it cannot be legally shipped to California. Ensure your engine build meets the specified requirements for compression, exhaust, and drivetrain to get the most out of this performance camshaft.
