SBF Xtreme Energy Hyd. Cam XE254H

The COMP Cams SBF Xtreme Energy Hydraulic Cam XE254H (part number 35-255-5) is a computer-controlled hydraulic flat tappet camshaft engineered for small block Ford engines seeking aggressive street and strip performance. This cam delivers 0.478-inch intake and 0.485-inch exhaust lift with 254/258-degree duration and a 114-degree lobe separation angle, operating effectively across a 1000 to 5200 RPM range. The Xtreme Energy designation indicates a profile optimized for high-revving applications while maintaining the reliability of hydraulic valve train technology.

Hydraulic flat tappet design eliminates complex valve lash adjustment requirements while providing consistent lift and duration across the RPM band. The 254/258-degree duration split and 114 LSA (lobe separation angle) produce strong mid-range and top-end power delivery characteristic of Xtreme Energy profiles. Computer-controlled manufacturing ensures precise grind specifications and repeatability across production, critical for tuning engines where marginal power gains matter. The cam's RPM range of 1000–5200 establishes it as suited for street-driven performance cars and bracket racing applications requiring broad torque delivery.

Small block Ford enthusiasts—from 289, 302, 351W, and compatible platforms—use this camshaft in builds targeting 350+ horsepower gains while retaining original valvetrain architecture. The hydraulic design accommodates stock or upgraded pushrods and rocker arms without requiring solid lifter conversion. Installers should verify spring pressures and valve clearance compatibility with the specific engine platform and confirm the SBF camshaft bore specification matches the block before installation.
