Product Details

The COMP Cams Mutha' Thumpr K33-601-5 is a complete camshaft kit engineered for Ford FE-Series engines (352-428 cubic inch). This hydraulic flat tappet camshaft delivers an aggressive idle and strong mid-range power with a 234/249 duration profile that provides excellent throttle response and a distinctive performance exhaust note.

Complete K-Kit Includes:

  • Hydraulic flat tappet camshaft with 234/249 degree advertised duration
  • Hydraulic lifters engineered for optimal performance
  • High-performance valve springs designed to match cam specifications
  • Precision-machined valve spring retainers
  • Valve locks (keepers) for secure installation
  • Valve stem seals for oil control
  • Timing chain set for precise valve timing
  • Assembly lube for proper break-in
  • Installation instructions and COMP Cams decals

The Mutha' Thumpr series is designed for street performance applications where an aggressive sound and strong acceleration are priorities. This cam profile works best with stock or mildly modified engines and provides excellent street manners while delivering that unmistakable performance idle. The K-Kit format provides everything needed for a complete valvetrain upgrade in one convenient package, eliminating the guesswork of component matching.

Application: Ford FE-Series V8 engines (352, 360, 390, 406, 410, 427, 428 cubic inch)

simply and quick

Best price I could find after hours of searching, I recommend 100%!!!

They had the best price on a hitch I was looking for and the shipping was fast also. The hitch was shipped bare except for taping the box of bolts to it thus leaving the hitch open and chipping the paint/powdercoating in quite a few places which I had to touch up before installing.

Easy to use website. The belts I ordered didn't have a picture but I knwew what I was looking for.
