BBC Extreme Energy Cam XE274H-10

The BBC Extreme Energy Cam XE274H-10 from Comp Cams is a high-performance hydraulic roller camshaft designed for big-block Chevy (BBC) engines, particularly those seeking aggressive street and strip performance. This camshaft is ideal for automotive enthusiasts and professional tuners looking for reliable valve timing control without the added complexity of adjustable timing systems.

The XE274H-10 features a precision-ground profile optimized for hydraulic roller lifter compatibility, ensuring consistent valve actuation and reduced wear on valve train components. Its design promotes increased intake and exhaust valve overlap, enhancing scavenging efficiency and improving cylinder filling, which are critical for maximizing power in naturally aspirated big-block engines.

This camshaft is particularly beneficial for cruiser builds, muscle car restorations, and dedicated street/strip engines where reliability and a broad powerband are essential. It integrates seamlessly with OEM-style timing chains and standard BBC heads, making it a versatile choice for various applications.
