Andrews Cam for Big Twin delivers more mid-range and top-end power for street and drag bikes while keeping idle unaffected up to 6,000 rpm with stock valve springs.

These cams are computer designed and precision ground from alloy steel billets on Landis CNC cam grinders in the USA.

• Works with solid or hydraulic lifters.
• Designed for mildly stroked motors or motors with head work done; compatible with stock hydraulics when spring travel is set to a minimum of 0.560".
• Installer must check coil bind, valve-to-valve clearance, and valve-to-piston clearance.
• 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-style components unless replaced as a set. Late '77 and later gear sets are identified by a circular groove machined in the outer face of the cam gear.

Made in the USA.
