BBC Extreme Energy Cam XE262H-10

The BBC Extreme Energy Cam XE262H-10 by COMP CAMS is a street-performance hydraulic flat-tappet camshaft engineered for big-block Chevrolet engines seeking responsive mid-range torque and reliable daily-driving characteristics. This cam is purpose-built for builders and enthusiasts who refuse to compromise between power gains and mechanical longevity. Whether you're upgrading a classic muscle car, a street rod, or a weekend cruiser, the XE262H-10 delivers the valve-event timing and lift profile needed to wake up a BBC without sacrificing drivability or fuel economy.

COMP CAMS engineered the XE262H-10 with a carefully calibrated lobe profile that balances intake and exhaust event timing to optimize cylinder filling and scavenging efficiency across the RPM band. The hydraulic flat-tappet design ensures self-adjusting valve clearance, eliminating the need for frequent adjustment and reducing wear on valve train components—a critical advantage on street engines running varied driving conditions. The cam's moderate lift and duration figures work harmoniously with stock or mildly modified cylinder heads, manifolds, and intake systems, making it an ideal choice for builds that prioritize reliability and real-world usability over peak-horsepower numbers alone.

Big-block Chevrolet owners—from 396 to 454 cubic-inch variants—will find the BBC Extreme Energy Cam XE262H-10 a bolt-in upgrade that requires only a roller timing chain, compatible pushrods, and proper valve-lash setup during installation. This camshaft pairs exceptionally well with stock or slightly ported heads, aluminum or cast iron intakes, and carbureted or light fuel-injection systems. Technicians and experienced DIY builders appreciate COMP CAMS' reputation for quality control and consistency, ensuring each cam meets exacting specifications for lobe centerline, lift, and duration. Installation requires standard engine-building knowledge; professional installation is recommended to verify proper timing-chain indexing and valve clearance.
