ANDREWS Cam C Grind Shovelhead 212620

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. Strokers from 84"- 96" will really turn on this cam. Broad torque range from 2000 - 7000+ rpm. 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.
