COMP Cams Camshaft CB 47S XE290S-10

This COMP Cams Xtreme Energy camshaft, part number 11-655-47, is a solid flat tappet grind designed for Chevrolet Big Block engines like the 396, 427, and 454. You get the camshaft itself, ready for installation into engines originally equipped with flat tappet camshafts. This camshaft is built for performance applications, aiming to increase responsiveness and provide more area under the lift curve compared to older designs.

The Xtreme Energy profile is engineered to boost torque and horsepower gains without significantly sacrificing everyday drivability. It's designed to maintain adequate vacuum for accessories like power brakes, making it a solid option for street-driven vehicles. While it works well in carbureted setups, you'll see the best performance when paired with aftermarket intake manifolds, lower gear ratios, headers, and a free-flowing exhaust system. This camshaft is particularly suited for pro-street or bracket racing applications, and it benefits from a good intake, headers, and a torque converter with a 3500+ stall speed.

This camshaft fits a wide range of Chevrolet vehicles from the late 1960s through the early 1990s, including popular models like the Chevrolet C10 Pickup, Chevrolet Impala, and Chevrolet Camaro, provided they have the correct Big Block engine configuration.
