Description

COMP Cams is bringing the muscle car sound back, and it's nastier than ever! 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 an ongoing quest to provide you with the performance and sound you demand, COMP Cams engineering team proudly introduces the Thumpr Series cam and lifter kits. The lobe profile and grind characteristics of these Thumpr camshafts use a combination of an early exhaust valve opening, a long exhaust duration, and a generous amount of intake and exhaust overlap to maximize the rough-idling characteristics of the cams. This gives you a seriously aggressive exhaust note without negatively impacting the power output or streetability of the engine. Thumpr camshafts are available in different grind profiles; each one will produce a rough, racy exhaust note and impressive amounts of horsepower and torque within a different rpm range. Thumpr Series cam and lifter kits deliver a substantial power increase over an identical hydraulic flat tappet grind without sacrificing reliability or ease of maintenance.

Product Overview

COMP Cams offers complete component-matched valve train kits that deliver unbeatable performance, durability and ease of installation. All cam kits are fully tested and manufactured to the strictest standards. Each kit’s components were specifically chosen as the best performance match for that particular camshaft so that you can reap the benefits of a perfectly matched “Power Engineered System.” *GK-Kit - Cam & Gear Kit* * Camshaft * Lifters * Gear Drive * Assembly Lube * Decals * Instructions
