BBC Hydraulic Camshaft 280AH

The BBC Hydraulic Camshaft 280AH from COMP CAMS is specifically designed for big-block Chevrolet engines, offering street and mild performance enhancements while ensuring reliability. This hydraulic roller camshaft is ideal for builders looking to improve valve timing and lift over stock options without compromising the smooth operation typical of hydraulic lifters. Whether you're working on a classic muscle car, street rod, or restoration project, this camshaft provides the responsiveness needed to elevate engine performance.

The 280AH designation indicates both the camshaft's 280-degree duration and its compatibility with hydraulic roller lifters. This proven design minimizes friction and wear compared to flat-tappet cams while maintaining zero valve lash adjustment during operation. COMP CAMS employs precision-ground lobes and optimized ramp profiles to improve cylinder filling and exhaust scavenging, resulting in enhanced volumetric efficiency across the RPM range.

This camshaft is particularly suitable for BBC (big-block Chevrolet) applications, including 396, 427, and 454 cubic-inch engines, where a balance between stock performance and full-race aggression is desired. Installation requires compatible hydraulic roller lifters and a valvetrain that supports this setup, ensuring optimal performance and reliability for your engine build.
