The COMP Cams CB Nx273HR-13 camshaft is optimized for street machines equipped for high-horsepower nitrous setups, higher stall converters and lower gearing. The manufacturer warns this camshaft is optimized for use with a melanized or nitrided distributor gear and is not compatible with cast or steel gears without similar surface treatment; using improper gears may void warranties or returns.
