Product Details

If you're looking to get more mid-range torque out of your Ford 429 or 460 Big Block engine for a performance street application, this COMP Cams Xtreme Energy camshaft is a solid option. This hydraulic roller camshaft features a 218/224 degree intake/exhaust duration, designed to wake up the powerband in the crucial mid-RPM range where you'll likely spend most of your time on the street. It's built for engines that already have headers installed, as the improved exhaust flow helps this cam really shine.

This camshaft is a well-built component from COMP Cams, a popular name in performance engine parts. It utilizes a hydraulic roller design, which generally offers better performance and durability compared to flat tappet designs due to reduced friction. The specific grind, XR270HR-10, is chosen to provide a noticeable improvement in torque between roughly 2500 and 5500 RPM, making your vehicle feel more responsive when accelerating from a stop or passing on the highway. While it's a performance camshaft, it's still designed to work with stock-style valve springs and retainers, simplifying installation for those rebuilding or upgrading their engine.

This camshaft fits a wide range of Ford and Mercury vehicles from the late 1960s through the late 1970s, including models like the Ford LTD, Mercury Marquis, and Lincoln Continental. It's important to note that this camshaft is not CARB approved and cannot be shipped to California. For optimal performance and longevity, ensure you use appropriate valve springs and lifters that match the camshaft's specifications, and always follow the manufacturer's break-in procedure.
