Product Details

The COMP Cams Mutha' Thumpr GK08-601-8 is a complete hydraulic roller camshaft kit engineered for small block Chevrolet engines with factory roller lifter provisions. This aggressive cam profile delivers 235/249 degrees of advertised duration, producing a radical lope idle and outstanding mid-range to top-end power for street/strip applications.

Key Features:

  • Hydraulic roller cam design for OE roller small block Chevy applications
  • 235/249 advertised duration provides aggressive sound and performance
  • Complete GK-Kit includes camshaft, lifters, springs, retainers, locks, and assembly lubricant
  • Mutha' Thumpr profile optimized for aggressive idle quality and strong acceleration
  • Designed for street performance with enhanced throttle response
  • Compatible with stock roller blocks (1987-up SBC with factory roller cam provisions)

This kit provides everything needed for a complete cam swap in one package, eliminating the guesswork of component matching. The Mutha' Thumpr series is ideal for enthusiasts seeking maximum idle attitude combined with serious performance gains in carbureted or fuel-injected applications. Recommended for engines with aftermarket intake, headers, and 9.0:1+ compression.

First of all, I can not believe how fast I recieved my order, 2 DAYS! Best of all, the instructions made it easy for a non mechanic like me to install.

They were Very quick and i was very happy with the service i got!! 9-10*

needed a delivery date couldn't confirm

Great customer service, item shipped quickly. Very satisfied.

I couldn't find these ARP studs anywhere else for this price! $20 less than ANYWHERE! Definitely coming back to shop at Autoplicity.

This is the easiest purchase I ever made. The visor is great and installation was a breeze. The service by Autoplicity was A-1. Shipping was better than standard. Will buy from them again.
