K12-602-4 - Comp Cams Thumpr Hydraulic Flat Tappet Cams

Thumpr Camshafts are the hottest cams to hit the streets in more than a decade. Applying a camshaft design originally created for sports car endurance racing, they incorporate early exhaust valve opening, long exhaust duration, and a generous amount of intake and exhaust overlap. Best of all, Thumprs will not negatively impact power output or streetability.
