Let's face it--few things serve to grab our attention at a car show or cruise night more than a car with a thumping, high performance idle. In fact, one of the most frequent questions fielded when customers call our tech line is, \"what camshaft will give my car that mean-sounding idle?\" In an ongoing quest to provide you with the performance and sound you demand, the COMP Cams engineering team proudly introduces the Thumpr series of camshafts. The Thumpr camshafts are a new series of hydraulic flat tappet camshafts. The lobe profile and grind characteristics of these new Thumpr camshafts use a combination of early exhaust valve opening, long exhaust duration, and a generous amount of intake and exhaust overlap to maximize the rough-idling characteristics of the cams. They give you a seriously aggressive exhaust note without negatively impacting the power output or streetability of the engine. Thumpr camshafts are available in three different grind profiles; each one will produce a rough, racy exhaust note and impressive amounts of horsepower and torque within a different rpm range. \u003cstrong\u003eSpecs:\u003c\/strong\u003eApplication: Ford 351C, 351M - 400M, 1970 - 83.    \u003cdiv\u003eCam Style: Hydraulic flat tappet\u003c\/div\u003e     \u003cdiv\u003eBasic Operating RPM Range: 2,200-6,100\u003c\/div\u003e     \u003cdiv\u003eIntake Duration at 050 inch Lif 234\u003c\/div\u003e     \u003cdiv\u003eExhaust Duration at 050 inch Lif 249\u003c\/div\u003e     \u003cdiv\u003eDuration at 050 inch Lif 234 int.\/249 exh.\u003c\/div\u003e     \u003cdiv\u003eAdvertised Intake Duration: 286\u003c\/div\u003e     \u003cdiv\u003eAdvertised Exhaust Duration: 304\u003c\/div\u003e     \u003cdiv\u003eAdvertised Duration: 286 int.\/304 exh.\u003c\/div\u003e     \u003cdiv\u003eIntake Valve Lift with Factory Rocker Arm Ratio: 0.519 in.\u003c\/div\u003e     \u003cdiv\u003eExhaust Valve Lift with Factory Rocker Arm Ratio: 0.503 in.\u003c\/div\u003e     \u003cdiv\u003eValve Lift with Factory Rocker Arm Ratio: 0.519 int.\/0.503 exh.\u003c\/div\u003e     \u003cdiv\u003eLobe Separation (degrees): 107\u003c\/div\u003e     \u003cdiv\u003eComputer-Controlled Compatible: No\u003c\/div\u003e     \u003cdiv\u003eGrind Number: 287TH7\u003c\/div\u003e     \u003cdiv\u003eValve Springs Required: Yes\u003c\/div\u003e     \u003cdiv\u003eCamshaft Manufacturers Description: Mutha Thumpr.
