Product Details

If you're looking to get more grunt out of your Ford 429 or 460 big block engine, this COMP Cams Xtreme Energy camshaft is a solid option. It's designed to give you a noticeable increase in torque right off the bottom and through the mid-range, making it feel much stronger when you're accelerating from a stop or passing on the highway. Plus, it's built to maintain a good, stable idle, so you won't have to worry about it being too rough for daily driving.

This camshaft features a 212 degrees of intake duration and 218 degrees of exhaust duration, with a .490 inch lift on both sides. These specs are chosen to work well with the breathing characteristics of the Ford 385 series engines, helping them produce more power without sacrificing drivability. It's a hydraulic flat tappet design, which is a common and reliable setup for these classic Ford V8s. COMP Cams is well-known for making durable valvetrain components, and this cam is built to last.

This camshaft fits a wide range of Ford and Lincoln vehicles from the late 60s through the mid-90s, including popular models like the Ford F-150, F-250, and LTD, as well as Lincoln Continental. Make sure to check the full fitment list to confirm it's right for your specific application. You'll want to ensure you have the correct valve springs and pushrods to match the camshaft's lift and duration for optimal performance and longevity.
