SBC Magnum Hyd. Roller Cam 270H-R10

The SBC Magnum Hydraulic Roller Cam 270H-R10 from COMP CAMS is designed for small-block Chevrolet enthusiasts who seek reliable, street-friendly performance. This hydraulic roller camshaft is ideal for engines running standard production or mildly modified long-block configurations, making it suitable for daily drivers and weekend warriors alike.

Engineered for consistent valve actuation, the 270H-R10 camshaft features a total duration of 270 degrees, which includes both intake and exhaust profiles. Its hydraulic roller lifter design compensates for thermal expansion, maintaining consistent valve clearance across varying engine temperatures and load conditions. The roller lobes reduce friction and wear, enhancing overall efficiency compared to traditional flat-tappet designs.

This camshaft is particularly beneficial for small-block Chevy platforms that utilize hydraulic roller lifter blocks or retrofit kits. It is essential to verify push-rod geometry and perform proper valve-lash or preload setup during installation to ensure optimal performance.
