Product Details

The COMP Cams Thumpr CL01-600-8 is a complete hydraulic roller camshaft and lifter kit engineered specifically for Chevrolet Big Block Gen VI engines. This aggressive cam delivers the iconic Thumpr sound with excellent low-end torque and a choppy idle that announces serious performance.

Camshaft Specifications:

  • Intake Duration: 227° at .050"
  • Exhaust Duration: 241° at .050"
  • Hydraulic roller design for reduced friction and increased durability
  • Optimized lobe profiles for enhanced throttle response
  • Designed for street performance and mild racing applications

Complete Kit Includes:

  • Hydraulic roller camshaft
  • Hydraulic roller lifters (16)
  • Assembly lube for proper break-in
  • COMP Cams decals
  • Detailed installation instructions

The Thumpr series is ideal for enthusiasts seeking that aggressive cam sound with strong street performance. The hydraulic roller design provides superior valvetrain control compared to flat tappet cams while maintaining reliability for daily driving. This cam works best with performance valve springs, upgraded pushrods, and a performance torque converter in automatic transmission applications.
