ANDREWS J Grind Cam — Intake & exhaust, 242° duration, 0.405"/0.425" lift – 48-69 Big Twin

The J Grind Cam delivers more mid-range and top-end power for street and drag bikes. 🔧

• Works with solid or hydraulic lifters; idle remains unaffected up to 6,000 rpm with stock valve springs.
• Computer designed and precision ground from alloy steel billets on Landis CNC cam grinders.
• Adds power throughout the rpm range while maintaining a smooth idle — ideal for mild street applications.
• Bolt in with no head work required.
• Made in the USA.

Important: 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 the breather valve gear was changed. These components are not interchangeable with earlier-style components unless replaced in set only. Late '77 and later gear sets are identified by a circular groove machined in the outer face of the cam gear. ⚙️
