S&S Cycle 48-69 BT 513G Camshaft

This BT 513G Camshaft is for 1954-'84 big twins with either the Hydraulic Conversion kit or the Cylinder Head Replacement kit for panhead engines. It is also replacement parts for P-Series and SH-Series engines. Since this kit includes 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 percent from the specified value.

• Quiet, dependable hydraulic valve train when used with S&S Hydraulic Conversion kits
