COMP Cams Camshaft CS 270L312 S7

Starting with a .312" lobe lift, this COMP Cams CS 270L312 S7 camshaft is built for performance, especially in short track racing where rules might limit lift to .480" or .500". It's designed for Chevrolet Gen 1 Small Block engines, covering a wide range of displacements from 262 up to 400 cubic inches. This camshaft is a solid choice if your engine uses a flat tappet valvetrain, but it's important to verify your specific application, as many later model engines (from the mid-80s onward) came factory-equipped with roller cams.

This is a solid flat tappet camshaft with a 244/248 degree duration at .050" lift. COMP Cams is a well-known name in performance engine components, and this camshaft is part of their Launcher Series, aimed at providing noticeable performance gains. It's constructed to be a durable part for performance builds, offering a good balance for street and strip applications where a flat tappet setup is desired. Remember to check your engine's specific valvetrain configuration before installation, as this camshaft is not compatible with factory roller setups or the LS-based engines.

For engines built between 1955 and 1957, there's a specific oiling groove requirement on the rear journal. If your engine falls into this category, you'll need to confirm if this camshaft meets that specific need or contact us for assistance with an alternative. This camshaft is not CARB approved and cannot be shipped to California.
