ANDREWS CAM, F GRIND/.450 INCH LIFT

.450" valve lift. Basicly an 'A' grind cam, but with delayed timing to help eliminate 'pinging'. More power than stock cam. Should install with no headwork (excl. 81-82). Note: For 81-82 models. The height of original stock H-D valve guides restricts spring travel (and valve lift) to .430" or lower.

Fits: > L77-84 Shovelhead
