Product Details
COMP Cams is well-known for making performance valvetrain components, and this Xtreme Energy 4/7 Swap camshaft is a solid option for your Chevrolet Big Block engine. This camshaft is designed for street/strip use and works well with engines originally equipped with flat tappet camshafts, fitting a wide range of vehicles like the Chevrolet Impala, Chevelle, and Camaro from the late 60s through the 70s, and even some later C/K series trucks. It's built for engines needing a 2800+ stall torque converter and at least 9.5:1 compression.
The XE284H-10 features a 240-degree intake duration and 246-degree exhaust duration, with a 110-degree lobe separation angle. This specific grind is known for its rough idle, which is a characteristic many performance enthusiasts look for in a street/strip build. The 4/7 swap design helps improve exhaust scavenging and can lead to better power output. It's a hydraulic flat tappet camshaft, meaning it uses standard lifters and doesn't require roller rockers, making it a more straightforward upgrade for many older Big Block applications.
Keep in mind that this camshaft is intended for performance applications and will result in a noticeable idle lope. It's important to ensure your engine setup can support the requirements, including the need for a higher stall speed torque converter. Also, note that this part is not CARB approved and cannot be shipped to California.
