The LS Hyd Roller Cam 3-Bolt .621 /.604 116 Degrees from CAM MOTION INC represents a purpose-built upgrade for serious LS engine builders and street performance enthusiasts. This hydraulic roller camshaft is engineered for engines running aftermarket cylinder heads and higher-flow intake manifolds where aggressive valve timing delivers measurable gains in mid-range and top-end horsepower. Whether you're building a street strip machine or optimizing a modified LS for road course duty, this cam profile bridges the gap between daily drivability and performance without requiring exotic fuel or extreme tuning.
The .621-inch intake valve lift and .604-inch exhaust lift specification provides excellent cylinder head scavenging and filling efficiency, while the 116-degree lobe separation angle offers a solid compromise between power band placement and idle quality. Hydraulic roller design eliminates the need for rocker arm geometry changes and delivers superior durability compared to flat-tappet designs, with the 3-bolt cam gear mounting pattern ensuring compatibility with most modern LS platforms including LS1, LS2, LS3, and LS9 applications. CAM MOTION's manufacturing process ensures consistent lobe profiles and hardened journals that withstand sustained high-RPM operation and extended track sessions without premature wear or valve float.
Installers should confirm that cylinder heads feature adequate valve seat concentricity and that pushrods are matched to the increased lift specification—mismatched combinations can result in valve train noise and reduced reliability. This camshaft pairs effectively with 1.6:1 rocker ratio heads, performance intake manifolds, and tuned exhaust systems that capitalize on the improved scavenging characteristics. Proper break-in procedure and adequate oil supply to roller lifters are critical; use quality assembly lube on lifters and verify oil pressure readings before start-up to ensure bearing longevity and peak performance delivery across the RPM band.
