What is the primary application for this COMP Cams camshaft?

This COMP Cams CS 300F-6 camshaft is specifically designed for drag racing applications on Chevrolet Small Block engines. It's intended for builds requiring high compression and high RPM operation, typically with ported heads and a high stall torque converter.

How do I know if my Chevrolet Small Block engine is compatible with this camshaft?

This camshaft fits GEN 1 Small Blocks but does not work with factory roller camshafts introduced from 1985 onward, nor LS-based engines. You will need to inspect your engine to confirm it has a flat tappet setup. Additionally, 1955-1957 models require a specific oiling groove that this cam lacks.

What compression ratio and stall speed are recommended for this camshaft?

For optimal performance, COMP Cams recommends a minimum compression ratio of 11.5:1 for this camshaft. It is also designed to work best with a torque converter that has a stall speed of 5000 RPM or higher.

Product Details

If you're building a drag-focused Chevrolet Small Block engine and need a camshaft that can handle serious abuse, this COMP Cams CS 300F-6 solid flat tappet camshaft is a solid option. It's designed for engines in the 350-400 cubic inch range, requiring at least 11.5:1 compression and a 5000+ RPM stall speed torque converter, especially when paired with ported cylinder heads. This camshaft offers a 270-degree intake and 278-degree exhaust duration at .050 lift, making it suitable for aggressive racing applications.

This camshaft is built for performance, featuring a solid flat tappet design that's common in many older Chevrolet Small Block engines. It fits a wide range of GEN 1 Small Blocks, including popular displacements like the 350 and 400. It's important to verify your engine's setup, as this camshaft is not compatible with factory roller camshaft blocks from 1985 and newer, nor is it designed for LS-based engines. Early 1955-1957 models also require a specific oiling groove that this particular camshaft does not have, so double-checking your block's specifications is key before installation.
