COMP Cams Camshaft CB 260H-10

This is the COMP Cams CB 260H-10 High Energy camshaft, designed for Chevrolet Big Block engines like the 396, 427, and 454 cubic inch V8s. If you're looking to improve the torque and power output of your classic Chevy, this camshaft is a solid option. It's particularly well-suited for towing applications, especially in 454 cubic inch engines paired with manual or automatic transmissions and 3.73 or higher axle ratios. You can expect a smooth idle, making it a comfortable choice for daily driving or weekend cruising.

This camshaft is a hydraulic flat tappet design, meaning it uses hydraulic lifters to maintain zero valve lash automatically. The grind features a 212 degrees of intake and 212 degrees of exhaust duration at .050 inch lift, which is a popular choice for achieving a good balance between low-end torque and mid-range power without sacrificing too much drivability. COMP Cams is a well-known name in performance engine components, and this High Energy series camshaft is built to provide reliable performance for a wide range of Chevrolet vehicles from the mid-60s through the mid-90s, including popular models like the Impala, Chevelle, and C10 pickups.

When installing this camshaft, remember that it's intended for engines originally equipped with flat tappet camshafts. If your 1965-1966 396 Big Block has an oiling groove in the rear journal, this specific part number will not fit. In those cases, you'll need to contact COMP Cams directly for a cam with that specific feature. Always refer to the manufacturer's installation instructions for proper break-in procedures and any specific hardware requirements.
