ANDREWS J Grind Cam — 242° duration, 0.405 in lift – 70-77 Big Twin

The J Grind Cam delivers more mid-range and top-end power for street and drag bikes, improving throttle response and overall performance. ⚙️

These cams are computer designed and precision ground from alloy steel billets on Landis CNC cam grinders to ensure consistent profiles and reliability.

They work with solid or hydraulic lifters and maintain a smooth idle up to 6,000 rpm with stock valve springs. The cams are bolt-in for mild street applications and require no head work.

Made in the USA. Always check coil bind, valve-to-valve clearance, and valve-to-piston clearance before installation. On late '77 and later engines, note the change in pitch diameter on camshaft and related gears; late '77 and later gear sets are identified by a circular groove machined in the outer face of the cam gear.
