SBF Extreme Energy Cam XE284H-10

The SBF Extreme Energy Cam XE284H-10 from COMP CAMS is a hydraulic roller camshaft engineered for small-block Ford (SBF) engines seeking aggressive street and strip performance. This is the choice for builders who demand reliable valve lift and duration without sacrificing streetability or demanding complex setup procedures. Whether you're building a 302, 347, or 408 stroker, this cam delivers the mechanical advantage needed to unlock hidden horsepower across the RPM band while maintaining safe valve train clearances and reasonable spring pressures.

COMP CAMS' Extreme Energy profile combines optimal ramp rates with proven lobe geometry to maximize volumetric efficiency without excessive lifter load or wear. The hydraulic roller design uses self-adjusting lifters that eliminate lash adjustment and reduce maintenance—critical for high-mileage engines or track vehicles where reliability cannot be compromised. The XE284H-10 designation specifies a particular lift and duration window optimized for 1.6:1 rocker ratios and standard head geometry; the robust 9.42 lb casting handles sustained high-RPM operation, and the precision-ground lobes ensure repeatable performance across the entire valve train.

Street and entry-level drag racers benefit most from this camshaft's broad power curve and forgiving nature under varying fuel quality and timing conditions. Installation requires standard small-block Ford cam bearing surfaces, compatible roller lifters, and a timing set rated for hydraulic roller cams; many builders pair this with a matching intake or carbureted fuel system to maximize response. Always verify lifter clearance and pushrods length during initial assembly, as improper setup can lead to valve float or lifter pump-up at high RPM.
