Product Details
The nitriding process on this COMP Cams camshaft gives its lobes a hard, wear-resistant surface. This is a solid flat tappet camshaft designed for Chevrolet Small Block engines, specifically those in the 327-358 cubic inch range with about 9:1 compression and a 2-barrel carburetor setup, assuming good intake and exhaust flow.
This camshaft features a 248 degrees of intake duration and 250 degrees of exhaust duration, with a 108-degree lobe separation angle. This combination is often referred to as a 'fast track' profile, suitable for oval track racing or performance street applications where quick valve events are beneficial. It's built for engines that use a flat tappet valvetrain, and it's important to verify your specific engine block's configuration, as GM transitioned to roller cams in many models starting in the mid-80s.
This camshaft fits a wide range of Chevrolet Small Block engines, including popular choices like the 350 and 327, found in vehicles such as the Chevrolet C10, Camaro, and Caprice. For 1955-1957 Chevrolet 265 engines, ensure there's an oiling groove on the fifth cam journal.
