BB Mopar Extreme Energy Cam CRBXE268H-10

The BB Mopar Extreme Energy Cam CRBXE268H-10 is a hydraulic flat tappet camshaft engineered for Mopar B and RB-series engines seeking high-RPM performance and aggressive valve timing. This COMP Cams offering is purpose-built for enthusiasts and builders who demand reliable lift and duration characteristics across a wide operating range. Whether you're rebuilding a classic Dodge, Plymouth, or Chrysler performance engine or optimizing an existing platform, this cam delivers the mechanical precision required for consistent, repeatable results in street and moderate competition applications.

Featuring a 268-degree intake duration and 280-degree exhaust duration with a 110-degree lobe separation angle (LSA), the BB Mopar Extreme Energy Cam produces intake lift of 0.477 inches and exhaust lift of 0.480 inches. The hydraulic flat tappet design eliminates the need for solid lifter conversion, maintaining compatibility with stock or upgraded valve train geometry while reducing overall system noise and wear. Operating range spans 1600 to 5800 RPM, providing low-end torque response without sacrificing mid-range and upper-RPM power delivery—a critical balance for street-driven applications where drivability matters as much as peak performance.

Engine builders and restoration specialists will find this camshaft ideal for 340, 360, 383, 400, and 440 Mopar applications where OEM or mild performance cams fall short. Installation requires proper valve train setup, including verification of pushrod length and rocker arm geometry to ensure optimal valve lift and prevent interference. The cam's moderate LSA and broad RPM band make it suitable for both naturally aspirated and lightly boosted platforms, offering versatility that appeals to street rodders, classic muscle car restorers, and weekend track enthusiasts alike. Correct break-in procedure using quality engine oil with zinc and phosphorus additives is essential for longevity and performance consistency.
