COMP Cams Camshaft CS 47S 288BR-7

If you're building a Chevrolet Gen 1 Small Block for serious oval track competition, the COMP Cams CS 47S 288BR-7 camshaft is a solid choice. This solid roller camshaft is specifically designed with a 4/7 firing order swap, which can help improve exhaust scavenging and overall engine balance. It's built for engines like the 350, 400, and other popular displacements in this family, offering a 258/264 degree intake/exhaust duration at .050 inch lift.

This camshaft is a roller type, meaning it uses roller lifters to reduce friction compared to flat tappet designs. This translates to more efficient power delivery and potentially longer engine life under demanding conditions. The 4/7 swap is a notable design feature for racers looking to optimize their engine's performance, especially at higher RPMs. It's important to confirm your specific engine block is a factory roller or has been converted, as this camshaft is not compatible with factory roller blocks from 1985 and newer, nor is it compatible with LT1/LT4 or LS-based engines.

When installing this camshaft, remember that 1955-1957 Chevrolet 265 engines require a specific oiling groove on the rear journal. If your engine falls into this category, you'll need to contact us for a special order. This camshaft is intended for off-road use and is not CARB approved, so it cannot be shipped to California. Ensure you have the correct valve springs, pushrods, and lifters to match this solid roller camshaft for optimal performance and reliability.
