COMP Cams Camshaft CS 47S 296TLS-6

This is the COMP Cams CS 47S 296TLS-6 solid flat tappet camshaft, designed for Chevrolet Small Block engines. It's built for drag racing applications and features a 4/7 firing order swap, which can help improve cylinder scavenging and overall performance on the track.

This camshaft is well-built for demanding use, featuring a 266-degree intake and 274-degree exhaust duration at .050 lift. The 4/7 swap design is a notable change from stock firing orders, often leading to improved exhaust port flow and a more consistent power band. It's important to confirm your engine's configuration, as this camshaft is intended for engines with flat tappet lifters and specific displacement ranges from 262 to 400 cubic inches. It will not fit factory roller camshaft blocks from 1985 and newer, nor LS-based engines.

For 1955-1957 Chevrolet engines, a rear journal oiling groove is required. If your block has this feature, you'll need to contact us directly to ensure you get the correct camshaft for your specific application.
