How do I know if my Chevrolet Small Block engine uses a flat tappet camshaft?

Engines built before 1985 generally use flat tappet cams, but some later models, especially in trucks and SUVs, retained them. The most reliable way to confirm is to remove the intake manifold or timing cover to visually inspect the camshaft and lifters.

This High Energy camshaft kit is designed to provide strong torque and improved fuel mileage, particularly with higher axle ratios. It offers a smooth idle, making it suitable for daily driving and street use.

Product Details

If you're looking to get more out of your classic Chevrolet Small Block engine, this COMP Cams High Energy camshaft kit is a solid option. It's designed to give you strong torque and improved mileage, especially with higher axle ratios, all while maintaining a smooth idle. This kit is a great way to wake up engines in a wide range of vehicles, from classic Camaros and Corvettes to trucks and custom builds.

This kit includes the CS 240H camshaft, lifters, a timing chain set, assembly lube, and decals, so you have the essential components for the job. The camshaft itself features a 192-degree intake and 200-degree exhaust duration, which is a popular choice for street-driven vehicles that need a good balance of power and drivability. It's specifically tuned for 262-305 cubic inch engines, but it also works well in larger displacements like the 350 and 400 cubic inch engines when paired with appropriate gearing.

It's important to note that this kit is for flat tappet camshafts. If your engine was built from 1985 or later, especially in performance models like Camaros and Corvettes, it might have come with a factory roller camshaft. You'll want to check your engine's configuration by removing the intake or timing cover to be sure before ordering. For 1955-1957 Chevrolet 265 engines, a specific oiling groove is required on the fifth journal; contact us if you have one of these early engines.
