SBC Cam 268H (Hyd)

The COMP Cams SBC Cam 268H hydraulic camshaft is a high-energy performance profile engineered for small-block Chevrolet engines requiring aggressive valve timing and reliable hydraulic actuation. This 268-degree duration camshaft delivers 0.454 inches of lift on both intake and exhaust lobes, optimized for engine speeds between 1500 and 5500 RPM with a 110-degree lobe separation angle. Built for enthusiasts and engine builders seeking increased horsepower and torque across a broad RPM band without sacrificing streetability.

The hydraulic flat-tappet design provides consistent valve actuation through hydraulic lifters, reducing the complexity of mechanical adjustment and eliminating the need for manual preload tuning. The symmetric 268/268 duration and equal 0.454/0.454 lift across both banks ensure balanced cylinder charging and scavenging, critical for efficient combustion and responsive throttle response. The 110 LSA (lobe separation angle) positions intake and exhaust events to maximize overlap without excessive valve overlap losses, resulting in predictable power delivery across the operating range. Weighing 8.84 pounds, this camshaft integrates directly into stock small-block Chevrolet engine blocks and head assemblies.

This profile is suitable for street and strip small-block Chevrolet builds—including hot rods, muscle cars, and performance trucks—where the 1500–5500 RPM power band covers both highway cruising and moderate track duty. Builders and restorers working with classic Chevrolet platforms will find this cam a capable middle-ground option that increases performance without requiring extensive engine modifications or high-rpm-only operation. Installation requires proper valve train setup, pushrod length verification, and timing confirmation to ensure correct mechanical advantage and longevity.

COMP Cams remains a recognized manufacturer within the automotive performance aftermarket, known for grinding precision and cam profile consistency. Verify compatibility with your specific small-block variant (262, 265, 267, 283, 302, 327, 350, 400) and confirm all ancillary components—lifters, pushrods, rocker arms, valve springs—meet the load and geometry specifications of this high-energy profile before installation.
