Andrews, F grind / .450" lift camshaft

.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 (NU)
