Schneider supplied the reproduction Boss 351 cam. Often inaccurately listed as .477 lift, the Boss 302 and Boss 351 share the same cam specs. The .477 lift value was achieved by multiplying the .298 lobe lift by the 1.6 ratio rocker offered in Windsor applications. When run with the 1.73 rockers used on the Cleveland, the actual lift was .515. The 290-degree advertised duration figure translated into roughly 230 degrees at .050.
