Bbc Cam 270h (Hyd)

The BBC Cam 270H (Hyd) from COMP CAMS is a hydraulic flat-tappet camshaft engineered for big-block Chevrolet engines seeking a blend of street manners and moderate performance gains. This cam is purpose-built for enthusiasts who want improved breathing without sacrificing reliability, idle quality, or streetability—making it ideal for restorations, weekend cruisers, and vehicles that see regular road duty. The 270-degree duration and hydraulic lifter design ensure straightforward installation and low maintenance, eliminating the complexity of solid-roller setups while delivering responsive mid-range power.

Hydraulic lifters automatically adjust for valve lash tolerance, providing consistent performance across temperature swings and eliminating the need for frequent adjustment—critical for daily drivers and vintage restorations where precision tuning may not be practical. The 270-degree intake and exhaust duration promotes efficient scavenging and cylinder filling without aggressive overlap that causes vacuum loss or cold-start instability. COMP CAMS' quality manufacturing ensures accurate lobe geometry and surface finish, reducing wear on rocker arms and pushrods while maintaining the durability expected from hydraulic designs that have proven themselves across millions of big-block miles.

This BBC Cam 270H is compatible with all standard big-block Chevrolet applications (396, 427, 454 cubic inches) using conventional hydraulic lifter valleys and timing covers. Installation requires a basic valve train refresh—new pushrods, rocker arms, and gaskets are recommended to ensure optimal performance and longevity. Whether you're building a street 454 for weekend cruising, restoring a classic muscle car, or seeking a reliable upgrade over an original camshaft, the BBC Cam 270H delivers the perfect balance of power and practicality for serious engine builders and DIY mechanics alike.
