Sbc Cam&Lifter Kit 268H (Hyd Lifter #812-16)

The COMP CAMS Sbc Cam&Lifter Kit 268H with Hydraulic Lifter #812-16 is a purpose-built camshaft and lifter assembly engineered for small-block Chevy engines demanding high-energy performance characteristics. This kit is designed for enthusiasts and mechanics seeking reliable valve actuation in street and light performance applications where hydraulic lifter technology provides automatic lash adjustment without manual valve clearance maintenance. The 268-degree duration rating on both intake and exhaust sides, paired with 0.454-inch lift specifications, delivers the aggressive timing curve necessary for increased horsepower and torque across the mid-to-upper RPM band.

The hydraulic flat-tappet design eliminates pushrod preload guesswork and engine wear associated with mechanical adjusters, making this kit ideal for street applications where consistent performance and durability matter. With a 110-degree lobe separation angle, the timing creates a broad power band between 1500 and 5500 RPM, optimizing throttle response and drivability across everyday and spirited driving conditions. Hydraulic lifter technology automatically compensates for thermal expansion and wear, ensuring optimal valve timing stability without periodic adjustment—a critical advantage in high-mileage or heavily used engines. The complete kit includes both camshaft and lifter components, eliminating compatibility risk and simplifying installation planning.

This assembly is exclusively compatible with small-block Chevrolet platforms using hydraulic lifter configurations, making it suitable for classic muscle cars, street rods, and modern restorations where original architecture is maintained. Installers should verify existing lifter type and bore compatibility before ordering; the #812-16 hydraulic lifter specification ensures proper seating in standard small-block Chevy lifter galleries. Professional engine builders and experienced enthusiasts will recognize this cam profile as a proven entry point into performance tuning without requiring extensive engine modifications, fuel system upgrades, or cylinder head work. Proper installation with quality engine oil and correct break-in procedures is essential to achieve rated performance and component longevity.
