Product Details

This COMP Cams Xtreme Energy camshaft features a 230-degree intake duration and 236-degree exhaust duration, designed for Ford's 429 and 460 Big Block engines. It's built for high-performance street applications, aiming to give you a very strong mid-range power band. This cam is a solid choice if you're looking to wake up your engine for spirited driving, especially when paired with headers and a stall converter around 2400 RPM.

The hydraulic flat tappet design means it operates with a self-adjusting valvetrain, simplifying installation and maintenance compared to solid lifter cams. COMP Cams is well-known for producing camshafts that offer noticeable improvements in engine performance. This particular grind is intended to provide a significant boost in the RPM range where you'll spend most of your time on the street, making it a popular option for enthusiasts looking for more responsive acceleration.

This camshaft fits a wide range of Ford and Lincoln vehicles from the late 1960s through the mid-1990s, including popular models like the Ford F-150, LTD, and Lincoln Continental. Always check the full fitment list to confirm compatibility with your specific year and model.
