WebFeb 26, 2016 · The rocker arm ratio multiplies (increases) the effective lift of the camshaft lobes. For example, a 0.310” lobe lift cam yields 0.496” of valve lift when using a 1.6 ratio rocker arm. Peak lift on most engine builds are constrained by engine design; A.To maximize valve clearance the piston crown can be modified. WebFor the two cams shown, the duration at a lift of 0.250 differs by 11 crank degrees. Besides, once you've got the valve train moving, slowing it down abruptly to reduce the lift will trigger vibrations and require stiffer valve springs to counteract the deceleration. Constraining the lift makes sense only when there are clearance issues.
