What type of lifters are required for this camshaft?

This COMP Cams camshaft is a solid roller camshaft, which means it requires solid roller lifters to operate correctly. Standard flat tappet or hydraulic roller lifters will not be compatible with this design.

Will this camshaft fit my 1986 Chevrolet 350 engine?

Factory roller camshafts were gradually introduced starting in the mid-1980s. While many 1985 and newer 305s and 350s came with roller cams, it's best to confirm if your specific 1986 engine has a factory roller setup or a flat tappet cam. You may need to remove the intake or timing cover to verify.

Are there any special considerations for 1955-1957 Chevrolet engines?

Yes, 1955-1957 Chevrolet 265 engines require a specific oiling groove on the rear journal. The standard part number listed may not fit these early models. If your engine requires this groove, you will need to contact us for a specific camshaft configuration.

Product Details

If you're building a Chevrolet Small Block engine for oval track racing, this COMP Cams CS 296B-R4 camshaft is a solid option to consider. It's designed to work with solid roller lifters and offers a specific profile for competitive use, aiming for strong performance in the mid-to-upper RPM range where many racing applications live. This camshaft is built for engines that demand a robust valvetrain and consistent power delivery lap after lap.

This camshaft features a 260-degree intake duration and 267-degree exhaust duration at .050 inch lift, with .900 inch lift on both intake and exhaust. These specifications are tailored for optimal airflow and cylinder pressure in performance racing engines. It's constructed from durable materials to withstand the rigors of racing, ensuring reliability when you need it most. Remember to verify your engine's specific configuration, as some early 1955-1957 models and factory roller blocks from 1985 and newer may require different setups or modifications.

This COMP Cams camshaft fits a wide range of Chevrolet Gen 1 Small Block engines, including popular displacements like the 350, 400, and 327. It's a popular choice for racers looking to extract maximum performance from their engines. Always consult your engine builder or refer to COMP Cams' detailed installation instructions to ensure proper setup and to identify any other components, such as valve springs and lifters, that may be needed to complement this camshaft's aggressive profile.
