Bbc Cam&Lifter Kit 305H (Hyd Lifter#812-16)

The BBC Cam & Lifter Kit 305H (Hyd Lifter#812-16) from COMP CAMS is a complete hydraulic roller cam and lifter assembly engineered for Big Block Chevrolet engines seeking reliable performance gains without complex solid lifter tuning. This kit exists to simplify the upgrade path for engine builders and enthusiasts who want genuine power improvement while maintaining the self-adjusting convenience of hydraulic lifters. Whether you're rebuilding a 454 or 427 for street duty, weekend cruising, or moderate track work, this matched set eliminates the guesswork of pairing individual components and ensures valve train stability across varying RPM ranges.

The 305H profile delivers solid mid-range torque and responsive throttle character typical of COMP CAMS' proven BBC cam designs. Hydraulic lifters automatically compensate for thermal expansion and wear, eliminating the need for frequent lash adjustments that plague solid roller conversions. The kit includes eight precision-machined lifters (number 812-16) that are honed to exacting tolerances, ensuring consistent oil pressure distribution and smooth follower action across the full valve lift curve. This matched pairing reduces valve train noise and promotes longer component life compared to mixing cam and lifter brands or generations.

BBC Cam & Lifter Kit 305H buyers are typically engine rebuilders, hot rod fabricators, and serious enthusiasts upgrading stock or worn camshaft assemblies in big-block Chevrolet platforms. Installation requires standard cam installation procedures and timing verification; lifters drop directly into existing lifter bores without modification. This kit pairs seamlessly with stock BBC cylinder heads, Edelbrock aluminum castings, or modern performance heads, making it a versatile choice for street cars, trucks, and marine applications where reliable, predictable performance matters more than extreme RPM capability.
