SBC Xtreme Solid Cam XS282S

The SBC Xtreme Solid Cam XS282S from COMP CAMS is a mechanical flat tappet camshaft engineered for small block Chevrolet engines seeking aggressive performance and extended RPM capability. Designed for enthusiasts building street and strip powerplants, this solid cam delivers the valve lift and duration needed to maximize airflow and horsepower across a broad operating range. The XS282S bridges the gap between mild street profiles and full-race specifications, making it ideal for carbureted or fuel-injected small block builds targeting serious horsepower gains.

This camshaft features 0.520-inch intake and 0.540-inch exhaust valve lift with 282- and 290-degree durations respectively, paired with a 110-degree lobe separation angle that optimizes scavenging and combustion efficiency. The mechanical flat tappet design demands solid valve lifters, traditional rocker arms, and precise pushrod geometry—a proven system favored by traditionalists and budget-conscious builders. Operating parameters span 2,400 to 6,800 RPM, allowing the cam to produce measurable torque off idle while supporting high-revving applications; the aggressive profile generates significant port velocities that enhance cylinder filling and exhaust evacuation at sustained engine speeds.

Best suited for experienced engine builders and performance shops, the SBC Xtreme Solid Cam XS282S demands compatibility verification with your valve train components, including lifter type, rocker arm ratio, and pushrods. Installation requires proper break-in procedures—a quality break-in oil or additive package is strongly recommended to protect cam and lifter surfaces during initial operation. This camshaft is compatible with all mechanical flat tappet small block Chevrolet platforms and pairs effectively with performance heads, intake manifolds, and carburetors or fuel injection systems tuned for this aggressive lift and duration profile.
