SBC Magnum Solid Roller Cam 268AR

The COMP Cams SBC Magnum Solid Roller Cam 268AR (part number 12-700-8) is a mechanical roller camshaft engineered for small-block Chevrolet engines seeking increased power output across a broad RPM range. This 268-degree duration cam delivers symmetrical lift of 0.525 inches on both intake and exhaust, with a 110-degree lobe separation angle optimized for responsive mid-range and upper-RPM performance between 2,000 and 6,000 RPM.

The mechanical roller design reduces friction and wear compared to flat-tappet alternatives, allowing sustained operation at higher valve velocities without camshaft or lifter degradation. The 0.525-inch lift specification provides significant valve opening while the 268-degree duration balances street drivability with performance gains. The 110-degree LSA (lobe separation angle) creates a power band suited to naturally aspirated small-block applications, making this cam compatible with stock or mildly modified induction and exhaust systems without requiring radical tuning adjustments.

This camshaft targets small-block Chevrolet owners upgrading from OEM specifications who want measurable horsepower and torque gains without committing to extreme duration profiles that sacrifice low-end response. The Magnum series from COMP Cams combines roller technology with practical street-performance specifications. Installation requires proper valve-train geometry verification, pushrods matched to lift and duration, and rocker arm alignment to ensure reliability. The 8.79-pound weight reflects a solid-roller design built for extended service life under performance conditions.
