Thumpr? Cams
Musclecar sound is back and nastier than ever;
Thumpr? Cams deliver incredible exhaust lope and impressive performance

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.
