About This Product
The Andrews S-grind camshaft delivers 0.370-inch valve lift for 1936–1947 Knucklehead engines. This is the Knucklehead equivalent of the popular Shovelhead B cam, making it a hot-street upgrade that provides significantly more mid-range and top-end power while retaining a smooth idle. It is a good choice for modified motors and small stroker builds, and works with stock valve springs. The cam bearings are ground to 0.8115 inches to fit stock bushings. If you want more pull from your Knucklehead without a full race build, the S-grind strikes an excellent balance between street manners and genuine performance.
Manufacturer part number: 212970.
