Thumpr Cams are designed to provide outstanding sound matched with unbeatable performance. They are available for a wide range of engine applications, including the most popular power plants for street rods.
Featuring specially engineered profiles for each unique engine, Thumpr Camshafts provide the perfect combination of early intake valve opening and long exhaust duration, with a generous amount of overlap. This maximizes any engine’s aggressive idling characteristics without negatively impacting streetability. The Thumpr Camshaft line has now been expanded to include classic street rod engines such as Buick Nailheads, Chrysler Hemis, Ford Y-Blocks and Flatheads, and many other popular options for classic GM applications. The cams come in three unique grinds known as Thumpr, Mutha Thumpr, and Big Mutha Thumpr; each level fits a more aggressive application with higher compression ratios, converter stall speeds and other upgrades such as gears, aftermarket intakes and headers. With cams available in hydraulic flat tappet, mechanical/solid flat tappet and hydraulic roller configurations, COMP Cams offers the perfect Thumpr cam for any street rod or traditional hot rod.
