If you plan to build a real Hot Rod out of your V series Big Twin Flathead, we have the cams for you. These 4 bad babies feature cam lobes profiled after those legendary KHK models from 1956 and spell horsepower. However, all lobes have been redsigned using modern computer cam design and smoothing techniques. Of course these are not drop-in parts but require an experienced mechanic, who checks and establishes all necessary tolerances, like lifter clearance, case clearance and valve to head clearance. The set comprises 4 cams, generator idler gear and the pinion gear.
