ANDREWS Cam - J Grind - Big Twin

Highlights

• More mid-range and top-end power for street and drag bikes. These cams work with solid or hydraulic lifters, and the idle remains unaffected up to 6,000 rpm with stock valve springs.
• Cams are computer designed and precision ground from alloy steel billets on Landis CNC cam grinders.
• Add more power throughout rpm range and maintain a smooth idle.
• For mild street applications.
• Bolt in with no head work.
• Made in the USA.
• 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.
