#1 Grind Low Compression Cam Harley Davidson FLH 1200 1978 1980

Features: Grind #1 low-compression version of the "A" grind cam for 74" and 80" models. Short duration and high lift combination offers broad torque across the entire RPM range. Designed for hydraulic lifters but can be run with solids. Duration measured @ .053" checking height. Made in the USA. On late '77 and later engines, the pitch diameter on the camshaft, pinion gear, and breather valve gear was changed. These components are not interchangeable with earlier styles unless replaced in sets. Late '77 and later gear sets are identified by a circular groove machined in the outer face of the cam gear..
