Cam bolts into 66-84 (except 80-81) Big Twin engines with no head work; on 80-81 engines the height of the stock H-D valve guides restricts spring travel (and cam lift) to .430" or lessSpring travel and clearance, plus clearance at main bearing boss must...

Great street cam, especially for 84/88-inch strokers with maximum torque from 2,200 to 6,500 rpmUpgraded version of the original #6 grind

These hydraulic lifter cams are capable of 6000-plus rpm with stock springs and no valve floatMade in the U.S.A.

Designed with a combination of shorter durations and higher lifts to offer the advantages of a broad torque output through the entire rpm rangeDesigned for hydraulics, but could be run with solidsGrind #1 is the low-compression version of an "A" grind...
