Sbc Cam K-Kit 280H (Hyd)

The COMP Cams Sbc Cam K-Kit 280H (Hydraulic) is a complete small-block Chevrolet camshaft kit designed for street and strip applications requiring reliable hydraulic flat-tappet valve actuation. This fully assembled kit includes the camshaft, hydraulic lifters, valve springs, timing set, and all components necessary for installation, eliminating the guesswork of component selection and compatibility.

Specifications include 0.480-inch lift on both intake and exhaust lobes, 280 degrees of duration on both valves, and a 110-degree lobe separation angle (LSA). The hydraulic flat-tappet design automatically maintains zero lash, eliminating the need for manual valve adjustment and reducing valve train wear during extended use. The RPM range of 2000–6000 positions this cam for powerband optimization in typical street engines and entry-level race builds. COMP Cams' engineering ensures smooth operation across the full RPM band while maintaining factory-style reliability and part compatibility with standard small-block Chevy cylinder heads and blocks.

This kit is engineered for builders and engine rebuilders restoring or upgrading small-block Chevrolet engines in street rods, vintage muscle cars, classic trucks, and daily-driver applications where balanced performance and dependability take priority over extreme high-RPM capability. The complete kit format streamlines installation by providing matched components that have been tested together, reducing variables in cam timing, spring preload, and lifter geometry.

Hydraulic flat-tappet systems remain the industry standard for small-block Chevy engine builds due to their forgiving nature, lower cost than roller systems, and proven longevity in both stock and modified applications. The 280/280 duration and 0.480 lift spec represents a genuine street-performance upgrade from factory specifications, delivering noticeable torque gains without compromising cold-start or idle characteristics typical of hydraulic designs.
