Hydraulic Roller Cam - SBC 266HR-14

The Hydraulic Roller Cam SBC 266HR-14 by COMP Cams is engineered for small-block Chevy engines seeking reliable mid-range power and improved valve train efficiency. This hydraulic roller camshaft delivers the responsiveness that street and performance builders demand, combining the durability of roller technology with the automatic lash adjustment of hydraulic lifters. Whether you're rebuilding a classic muscle car, upgrading a daily driver, or fine-tuning a weekend cruiser, this cam provides the foundation for responsive throttle feel without the complexity of solid lifter adjustments.

COMP Cams' 266HR-14 designation reflects its aggressive yet streetable profile: 266 degrees of advertised duration with a moderate lift curve optimized for roller follower geometry. The hydraulic roller design eliminates the friction losses inherent in flat-tappet designs, allowing tighter valve timing and reduced wear on critical engine components. Roller lifters ride on needle bearings, distributing loads across hardened cam lobes and steel pushrods more efficiently than conventional designs. The cam blank is precision-ground from quality steel and heat-treated to withstand sustained RPM and valve spring pressure, ensuring longevity even in high-revving applications.

This camshaft is ideal for small-block Chevy builds running hydraulic roller lifters and compatible cylinder heads with standard valve spacing. Installation requires a quality cam bearing set, proper break-in oil with anti-wear additives, and verification of valve-to-piston clearance during initial assembly. The SBC 266HR-14 works seamlessly with stock or mildly ported heads, carbureted or fuel-injected induction systems, and naturally aspirated or moderately boosted configurations. Builders installing this cam should verify lifter bore specifications and ensure all pushrods are adequate for the application's intended RPM ceiling and valve spring pressures.
