![]() ![]() ![]() This reduces side loading, friction and wear on the valve stems and guides. What’s more, the longer the valve side of the rocker, the larger the diameter of the arc it follows as it moves up and down. A higher rocker ratio also reduces the amount of camshaft torque it takes to open the valves for a given amount of lift. The advantage of using higher ratio rocker arms is that the same cam lobe profile can produce more total valve lift for more power.Ī higher ratio rocker arm also requires less lifter and pushrod travel to achieve the same amount of lift as a lower ratio rocker. The 1.5 ratio rocker arms multiply the lift (.320 x 1.5) to achieve the. 480˝ of total lift at the valve, the cam itself is only producing about. If you’re using a typical street performance cam in a smallblock Chevy V8 that produces.
