The COMP Cams CS 291T Thumpr camshaft is a street/strip performance cam that delivers aggressive idle and broad midrange torque. It requires roughly 9:1 compression and a 2500+ rpm stall converter, plus supporting intake, gears and headers; expect a rough idle. Important: this cam is optimized for use with a melanized or nitrided distributor gear and is not compatible with untreated cast or steel gears.
