BBC Xtreme Solid Cam XS282S

The BBC Xtreme Solid Cam XS282S from COMP CAMS is a high-performance mechanical flat tappet camshaft engineered for big block Chevy engines demanding aggressive valve lift and extended duration. This camshaft is purpose-built for enthusiasts and engine builders seeking maximum power extraction across a broad RPM band, making it ideal for street performance, strip racing, and high-output engine builds where traditional cam profiles fall short.

Featuring 0.590-inch intake and 0.598-inch exhaust lift with a duration rating of 282 degrees intake and 290 degrees exhaust, the XS282S delivers commanding valve timing and aggressive flow characteristics. The 110-degree lobe separation angle (LSA) is tuned for solid lifter operation, maximizing scavenging efficiency and cylinder filling at peak horsepower points. Solid cam design eliminates hydraulic lag found in hydraulic lifter systems, enabling precise valve event control and responsiveness. The camshaft operates effectively across the 2400 to 6800 RPM power band, providing strong bottom-end torque while maintaining high-RPM breathing capability essential for performance applications.

This camshaft is compatible exclusively with big block Chevy engines equipped with solid lifter valve train geometry and mechanical configuration. Installation requires proper lifter selection, pushrods, rocker arm ratios, and valve spring rates matched to the XS282S profile to ensure reliable operation and prevent valve float at high RPMs. Professional engine builders and experienced rebuilders benefit most from this aggressive grind; improper installation or inadequate supporting components may result in valvetrain failure. Verify compatibility with your specific block, head casting, and intake manifold before purchase.
