Product Details

The COMP Cams Thumpr CL20-600-9 is a complete hydraulic roller camshaft and lifter kit engineered specifically for Chrysler small block 273-360 cubic inch V8 engines. This kit delivers the signature Thumpr aggressive idle sound with improved throttle response and mid-range torque, making it an ideal choice for street performance and muscle car applications.

Camshaft Specifications:

  • Intake Duration: 227 degrees at .050"
  • Exhaust Duration: 241 degrees at .050"
  • Hydraulic roller design for reduced friction and increased valve train stability
  • Distinctive choppy idle characteristic of the Thumpr camshaft series
  • Optimized lobe profiles for enhanced street performance

Complete Kit Includes:

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

This kit provides everything needed for the camshaft and lifter installation on Chrysler 273, 318, 340, and 360 cubic inch engines. The hydraulic roller design eliminates the need for break-in procedures required by flat tappet cams while providing superior durability and performance. The Thumpr camshaft series is designed for enthusiasts seeking that classic hot rod idle with excellent street manners and power delivery from idle to 5,500 RPM.

Easy ordering with PayPal! Thanks!

Easy navigating and great price.

very easy to find part, price reasonable....hopefully quick shipping too thank you

I needed a new passenger door handle since apparently my old one was made of butter. This site is great!

I paid for 2nd day shipping and 5 days later they were shipped out. So, I should receive my rotors in a full week from when I paid for 2 day shipping. I called customer service and they discounted the shipping rate to ground service. At least they were polite and helpful in the phone.

Great so far! Prices are very reasonable!

I RECEIVED GREAT SERVICE WITH AUTOPLICITY. THERE WAS AN ITEM ON THEIR WEBSITE THAT SAID OUT OF STOCK SO I CALLED AND ASKED WHEN THEY WOULD BE GETTING MORE AND THEY GUY WAS VERY POLITE AND HELPFULL. NOT TOO MENTION THE PRICE WAS WAY BELOW THEIR COMPETITORS. I WOULD RECOMMENT AUTOPLICITY TO ANYONE AND I WILL CONTINUE TO DO BUSINESS WITH THEM.
