Product Details

COMP Cams is well-known for its performance engine components, and this Magnum 260/260 solid flat tappet camshaft kit is a prime example of their expertise. Designed for Ford FE engines, this kit is built for those looking to create a serious street machine or a dedicated Pro Street car. If you're aiming for a radical idle and significant performance gains, this camshaft kit is engineered to deliver.

This kit includes everything you need to get your camshaft upgrade underway: the camshaft itself, a set of lifters, a complete timing chain set, assembly lube to ensure proper initial lubrication, and decals for that finishing touch. It's intended for use with a 3500+ RPM stall torque converter or a 4-speed manual transmission, and requires an 11.5:1 compression ratio with low gearing to perform at its best. This setup is not for the faint of heart; expect a very noticeable, aggressive idle that signals serious performance.

This kit fits a wide range of Ford FE engines, including popular applications like the 352, 390, and 428 cubic inch V8s found in vehicles such as the Ford Mustang, Fairlane, and F-Series trucks from the mid-60s to mid-70s. While this kit is designed for maximum performance, it's important to note that it is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's instructions for proper installation and break-in procedures.
