BBC Roller Camshaft CB 324IR-10

The COMP CAMS BBC Roller Camshaft CB 324IR-10 is a precision-engineered roller cam designed for big-block Chevrolet engines demanding high-performance street, strip, or racing applications. This camshaft serves builders and enthusiasts who need reliable valve actuation over a wide RPM band without sacrificing durability or ease of installation.

The roller design reduces friction and wear on lifters and pushrods, making it an ideal choice for both stock-block modifications and serious engine builds targeting improved power delivery and longevity. Roller camshafts like the CB 324IR-10 utilize specially hardened steel and precision-ground lobes to optimize valve timing, lift, and duration characteristics. This design allows for higher RPM operation and more aggressive lobe profiles while maintaining mechanical reliability.

Builders working on big-block Chevrolet platforms—including 427, 454, and 502 cubic-inch engines—will find the CB 324IR-10 suitable for carbureted or EFI applications requiring moderate-to-aggressive performance. The roller technology is especially effective in street engines where reduced parasitic loss directly translates to improved fuel efficiency and cooler running temperatures. This camshaft is a reliable choice for those looking to enhance their engine's performance.
