What is the main difference between this camshaft and a roller camshaft?

This is a solid flat tappet camshaft, meaning it uses a simple, durable design with a flat lifter that slides across the cam lobe. Roller camshafts use roller-tipped lifters, which reduce friction and can allow for more aggressive cam profiles and higher RPMs.

Does this camshaft come with lifters or other installation hardware?

This camshaft is sold individually and does not include lifters, valve springs, or other installation hardware. You will need to ensure you have compatible components or purchase them separately.

How can I tell if my Chevrolet Small Block has a flat tappet or roller camshaft?

The easiest way to confirm is to remove the intake manifold or timing cover. If the lifters are flat on the bottom and slide across the cam lobes, it's a flat tappet. If the lifters have a roller wheel on the bottom, it's a roller camshaft.

Product Details

This COMP Cams CS 270Xo-8 camshaft features a 240/242 duration at .050 inch lift, a solid flat tappet design, and is intended for Chevrolet Small Block Gen 1 engines. It's built for oval track racing and is designed to work with 327-358 cubic inch displacements, a 9:1 compression ratio, and a 2-barrel carburetor with stock intake and headers. This camshaft is a well-built option for those looking to enhance their engine's performance in a racing environment.

The CS 270Xo-8 is a popular choice for builders aiming for a noticeable improvement in their engine's power band. Its specifications are tailored for applications where consistent performance and durability are key. Remember that some earlier 1955-1957 SBC models require a specific oiling groove on the rear journal, and this particular camshaft does not fit those specific early blocks. Always confirm your engine's journal type before installation.

This camshaft fits a wide range of Chevrolet Gen 1 Small Block engines, including popular displacements like the 350, 327, and 400 cubic inch variants. It's important to note that it does not fit LT1/LT4 engines or factory roller small blocks from 1985 and newer, nor does it fit any LS-based engines. Verifying your engine's camshaft type, whether flat tappet or roller, is crucial for proper fitment.
