The COMP Cams 4 Pattern OE Hydraulic Roller Camshaft is a high-performance camshaft intended for small block Chevy, big block Chevy, and small block Ford carbureted or fuel injected applications. The Four-Pattern OE Hydraulic Roller camshaft is specifically designed to optimize the air intake and get the most power from the engine by preventing valves from closing too early or too late. The first series of cams devised to support a difference in runner length and avoid inefficient valve closing time, the Four-Pattern OE Hydraulic Roller Camshaft optimizes valve events, and highlights a huge improvement in the area under the curve and stability at high rpm. It is designed with four different lobe patterns, with an intake and exhaust design for both Out Board and inboard runners. Integrating a design that has boosted the performance of NASCAR racers for years, the COMP Cams Four-Pattern OE Hydraulic Roller Camshaft bestows this same technology to street vehicles to balance the air/fuel ratio per cylinder.
