BBC Cam&Lifter Kit 270H (Hyd Lifter #812-16)

The COMP Cams BBC Camshaft and Lifter Kit 270H (Hyd Lifter #812-16) is a complete hydraulic flat tappet camshaft and lifter assembly designed specifically for big block Chevrolet engines. This kit combines a precision-ground 270-degree duration camshaft with hydraulic flat tappet lifters, ensuring reliable valve actuation across the engine's operating range from 1500 to 5800 RPM. Engine builders and restorers can benefit from this ready-to-install solution that targets moderate performance gains without sacrificing streetability.

The 270-degree duration specification on both intake and exhaust lobes with a 110-degree lobe separation angle produces 0.510-inch lift per cylinder. This camshaft profile generates consistent power band characteristics and supports efficient scavenging across mid-range RPM, which is ideal for most street and light performance applications. The hydraulic flat tappet design automatically compensates for thermal expansion and mechanical wear, eliminating the need for manual valve lash adjustment and reducing maintenance complexity.

This kit is perfect for big block Chevy engine builders restoring original muscle cars, upgrading tired stroker builds, or assembling turnkey performance packages where proven component compatibility is essential. The #812-16 hydraulic lifter assembly is engineered to work within OEM pushrod geometry while providing enhanced reliability compared to worn solid tappet configurations. With this kit, enthusiasts can achieve a balance of performance and reliability in their builds.
