ANDREWS Cam for Big Twin — Intake 244°, Exhaust 256°, AB grind, gear type – 48-69 Big Twin

Cam for Big Twin delivers more mid-range and top-end power for street and drag bikes. 🔧🏁

These cams work with solid or hydraulic lifters and keep the idle unaffected up to 6,000 rpm with stock valve springs.

Computer designed and precision ground from alloy steel billets on Landis CNC cam grinders. Made in the USA.

Before installation, 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 the 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.

Bolt-in street cams feature an "A" intake and long-duration exhaust for cooler running and high-end power, suitable for hydraulic lifters.
