Product Details

The COMP Cams K51-602-11 Big Mutha' Thumpr Camshaft K-Kit delivers aggressive performance for Pontiac 265-455 cubic inch V8 engines. This hydraulic roller camshaft features a 243/257 duration split designed to produce the signature "thumping" idle and strong mid-range to top-end power that the Thumpr series is known for.

Complete K-Kit Includes:

  • Hydraulic roller camshaft with 243/257 duration profile
  • Hydraulic roller lifters matched to cam specifications
  • Performance valve springs for increased RPM capability
  • Steel retainers and valve locks
  • Valve stem seals for positive oil control
  • Timing chain set for precise cam timing
  • Assembly lube for proper break-in
  • Installation instructions and COMP Cams decals

The Big Mutha' Thumpr series is engineered for street performance enthusiasts who want an aggressive sound and improved throttle response. The hydraulic roller design provides durability and reliability while eliminating the maintenance requirements of solid lifter camshafts. This complete kit ensures all valvetrain components are properly matched for optimal performance and longevity in Pontiac applications.

Application: Pontiac V8 engines, 265-455 cubic inches. Verify compatibility with your specific engine configuration before installation.
