Cam Lifter Type at Lucy Brodie blog

Cam Lifter Type. The basic function of a valve lifter is pretty simple. In sohc (single overhead cam) setups you'll see a single camshaft driving rocker. Cam lobe lift, also called gross lift, is the distance a cam moves a lifter/tappet. The size and shape of the cam lobe under the lifter (multiplied by the ratio of the rocker arms) determines valve lift and duration. Determining what lifter is best suited for your application may be limited by your engine block to some extent (a vintage block cannot use. Sohc are higher performance and lighter (and so typically have a higher rev range) than underhead cams with lifters. It sits on the camshaft and transfers the motions of the cam lobe up through the pushrods and rockers to open and close the valves. Camshafts and lifters are available in two basic formats—roller and flat tappet. And then within those two formats, they can either be of the mechanical (solid), or hydraulic variety. Because a rocker arm multiplies the movement of the tappet, valve lift is not the same as cam lobe lift.
