Thumpr Cams

Musclecar sound is back and nastier than ever;

Thumpr Camshafts are a new series of retro-fit hydraulic roller and hydraulic flat tappet cams designed for use in Small & Big Block Chevy, Ford 351 Windsor and Small Block Chrysler engines. The aggressive exhaust note of a Thumpr cams comes from a combination of early exhaust valve opening, long exhaust duration and a generous amount of intake and exhaust overlap - maximizing the rough-idling characteristics of the cams without negatively impacting power or streetability.
