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

This is a solid flat tappet camshaft, meaning it uses a flat lifter that slides directly on the cam lobe. Factory roller camshafts use roller lifters that roll on the lobe, reducing friction. This COMP Cams camshaft is designed for engines originally equipped with flat tappet setups.

Does this camshaft come with lifters or other installation hardware?

This part number is for the camshaft only. Lifters, valve springs, pushrods, and timing sets are typically sold separately and must be chosen to match the camshaft's specifications for proper operation.

What is the recommended compression ratio for this camshaft?

This camshaft is designed to work well in engines with approximately 10:1 compression. Using it with significantly lower or higher compression ratios may affect performance and require tuning adjustments.

Product Details

If you're building a drag car with a Chevrolet Small Block and need a camshaft that can handle a heavier vehicle while still providing good torque, the COMP Cams CS 280S-8 is a solid option. This camshaft is designed for applications with around 10:1 compression and typically works well with a 3000+ stall torque converter, making it suitable for serious drag racing builds.

This particular camshaft features a 242-degree intake duration and 250-degree exhaust duration, with a solid flat tappet design. It's built to fit a wide range of Chevrolet GEN 1 Small Block engines, including popular displacements like the 350, 400, and smaller variants. COMP Cams is known for well-built valvetrain components, and this camshaft is no exception, offering a strong profile for performance builds.

It's important to confirm your specific engine block is a flat tappet design, as many later model Small Blocks (from 1985 and newer) came factory-equipped with roller camshafts, which are not compatible with this part. Also, early 1955-1957 Chevrolet engines require a specific oiling groove on the rear journal that this particular camshaft does not have. If you're unsure about your block's configuration, it's always best to check the timing cover or intake manifold area before ordering.
