The COMP CAMS SBF Xtreme Energy Hydraulic Roller Cam XE258HR (part number 35-510-8) is a purpose-built hydraulic roller camshaft engineered for small block Ford engines seeking solid mid-range power delivery with proven reliability. This cam delivers 0.533-inch intake and 0.544-inch exhaust valve lift, with a 258/266-degree duration split and 112-degree lobe separation angle, optimized to produce responsive power between 1,300 and 5,300 RPM—the effective operating window for street and light performance applications.
Hydraulic roller technology provides self-adjusting valve lash compensation, eliminating the need for manual adjustment and reducing wear on valve train components. The asymmetrical lift profile (intake 0.533" vs. exhaust 0.544") is calibrated to balance cylinder filling with exhaust scavenging. The 112-degree LSA (lobe separation angle) maintains a broad torque band, making this cam suitable for engines where drivability and fuel efficiency matter alongside performance. COMP CAMS' Xtreme Energy series represents a proven platform with millions of installed hours across the small block Ford community.
This camshaft is designed for small block Ford applications (Windsor and earlier variants) where builders want genuine performance gains without the complexity of adjustable valvetrain components. Users restoring stock motors to factory-plus power levels or building modest street engines will find the RPM range and lift characteristics well-suited to standard induction and exhaust systems. The hydraulic roller design is the modern standard for reliability in this segment and requires no special machine work or exotic supporting modifications.
Verify small block Ford compatibility with your specific year and block variant before ordering. Camshaft installation requires proper degree-setting, valve clearance setup, and timing chain verification to ensure correct valve event positioning. Professional installation is recommended to achieve optimum performance and longevity.
