BBM Xtreme Energy Hyd. Cam XE275HL (1-Bolt)

The COMP Cams BBM Xtreme Energy Hydraulic Cam XE275HL (1-Bolt) for Mopar B/RB-Series engines delivers aggressive valve lift and duration designed for street and strip performance in mid-range RPM bands. This hydraulic flat tappet camshaft produces 0.545 inches of lift on both intake and exhaust sides, with a 285-degree intake duration and 297-degree exhaust duration, engineered to generate substantial torque and horsepower across the 2500 to 6200 RPM operating window. The 110-degree lobe separation angle optimizes valve overlap for consistent performance characteristics across varying engine speeds and loading conditions.

The hydraulic design eliminates the need for lifter preload adjustments common in solid lifter profiles, reducing setup complexity and maintenance demands in the field. The aggressive intake and exhaust durations work in concert to improve cylinder scavenging efficiency while the moderate lift values maintain compatibility with stock or mildly modified valve train components, including pushrods and rocker arms. This cam profile delivers broad torque characteristics rather than peaky top-end power, making it responsive to load demands across typical driving and off-road scenarios where sustained mid-range performance matters more than maximum RPM numbers.

Builders and operators restoring or modifying classic Mopar B and RB-Series engines—whether for street vehicles, emergency service units, or performance platforms—select this camshaft profile for balanced power delivery without requiring extensive machine work or expensive valve train upgrades. The single-bolt design ensures straightforward installation on compatible engine blocks. COMP Cams' Xtreme Energy line is known in high-performance circles for achieving reliable power gains with factory-adjacent durability, making this cam a practical choice for operators seeking measurable performance improvement within proven engineering limits.
