Product Details

The COMP Cams K31-601-5 Thumpr 227/241 hydraulic flat tappet camshaft K-Kit is a complete cam and valvetrain kit. The Thumpr grind is built for high performance street use and gives a choppy, thumping idle. It has 227/241 duration at .050" (intake/exhaust).

Key Features:

  • Hydraulic flat tappet cast iron camshaft from the Thumpr series
  • Duration at .050" of 227 intake / 241 exhaust
  • 2,000-5,800 RPM operating range
  • Early intake valve opening and long exhaust duration create overlap for a hard-hitting exhaust note
  • Works with a stock converter, but performs best with a 2000+ stall converter and more rear gear

Complete K-Kit Includes:

  • Camshaft
  • Lifters
  • Valve springs
  • Retainers
  • Valve locks
  • Valve stem seals
  • Timing chain set
  • Assembly lube (in flat tappet applications)
  • Decals and instructions

Because the kit is matched to the camshaft, it covers the main parts of a cam swap in one part number. New flat tappet cams need new lifters, and the kit includes them.
