S&S 600G Camshaft HD Electra Glide 1965-75, 1982

These camshafts are for 1954–'84 big twins with either the Hydraulic Conversion kit or the Cylinder Head Replacement kit for panhead engines. They are also replacement parts for P-Series and SH-Series engines. Since these kits and engines include 1984–'99 style hydraulic lifters,the larger late style roller diameter requires that cams designed for 1984–'99 models must be used to achieve correct valve timing. When choosing a late style cam for this type of engine, be aware that, due to the approximate 1.5:1 rocker ratio of most aftermarket rocker arms for shovelheads, the total valve lift will be reduced by about 9% from the specified value. The specification chart shown here shows specs as used in a pan or shovel engine.
