COMP CAMS PART NUMBER #CLP-12-601-4

BRAND NEW IN THE BOX COMP CAMS FLAT TAPPET HYDRAULIC Mutha Thumpr™ CAMSHAFT, LIFTERS, AND PUSHRODS FOR SMALL BLOCK CHEVY ENGINES 262-400.

COMP Cams® Mutha Thumpr™ Hydraulic Flat Tappet Camshaft Kit

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 CAM HELP® tech line is “what camshaft will give my car that mean-sounding idle?” In their ongoing quest to provide customers with the performance that they demand, the COMP Cams® engineering team proudly introduces the Thumpr™ series of camshafts.

The reason that the new Thumpr™ Camshafts have such an aggressive exhaust note is that the lobe profiles and grind characteristics chosen by the COMP Cams® engineers produce 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 without negatively impacting the power output or streetability.

Thumpr™ Camshafts are available in three different grind profiles for each engine, all of which will produce a rough, racy exhaust note and impressive amounts of horsepower and torque at a specific rpm range.

Ecurie Ecosse racing car collection sells for £8.8 million

Tue, 03 Dec 2013

Ecurie Ecosse is a name that will need no introduction to classic motorsport fans. Established in 1952 by Edinburgh racing driver and businessman David Murray and mechanic Wilkie Wilkinson, this racing team is famous for two things – its stunning Flag Blue Metallic paint scheme and winning the 24 Hours of Le Mans. In fact, Ecurie Ecosse won Le Mans twice – back-to-back in 1956 and 1957, securing two of the three victories there for Jaguar’s D-Type.
