COMP Cams Camshaft CS 298Rx-6

If you're building a late-model, 400+ cubic inch oval track engine for your Chevrolet Small Block, this COMP Cams CS 298Rx-6 solid roller camshaft is a solid option. It's designed for engines with good cylinder heads and lighter valves, aiming to give you an improved power band for racing applications. This camshaft is a popular choice for those looking to extract more performance from their Gen 1 Small Block Chevy.

This camshaft features a 265/272 degree duration split and is a solid roller design, which generally allows for more aggressive lobe profiles and higher RPM capability compared to hydraulic flat tappet cams. The 50mm bearing journal size is standard for many performance applications. It's important to note that this camshaft is intended for engines that do not have the factory roller lifter setup from 1985 and newer, and it does not fit LS-based engines. For 1955-1957 models, a specific oiling groove is required on the rear journal, and this particular part number does not include it; please contact us if your early block requires this feature.

When installing this camshaft, ensure your engine is set up for a solid roller valvetrain, including the correct lifters, pushrods, and valve springs. It's also crucial to confirm your engine block's configuration to ensure compatibility, especially regarding the factory roller versus flat tappet setup. This camshaft is designed to work with engines that have good flowing cylinder heads and are typically in the 400+ cubic inch range, often found in dedicated racing builds.
