Product Details

The COMP Cams Thumpr CL35-600-8 is a complete camshaft and lifter kit engineered specifically for Ford 351 Windsor small block engines. This hydraulic roller cam delivers an aggressive 227/241 duration split that produces the signature Thumpr idle sound while maintaining excellent street manners and drivability.

Camshaft Specifications:

  • Advertised Duration: 279°/293° intake/exhaust
  • Duration at .050": 227°/241° intake/exhaust
  • Valve Lift: .525"/.540" intake/exhaust (with 1.6 rocker ratio)
  • Lobe Separation Angle: 112°
  • RPM Range: 1,800-5,400 RPM
  • Hydraulic roller design for reduced friction and improved durability

Complete Kit Includes:

  • Hydraulic roller camshaft
  • 16 hydraulic roller lifters
  • Assembly lube for proper break-in
  • COMP Cams decals
  • Detailed installation instructions

The Thumpr series is designed for enthusiasts who want that classic hot rod lope at idle with strong midrange torque. This cam works exceptionally well in street machines, mild street/strip applications, and vehicles with automatic or manual transmissions. The hydraulic roller design eliminates the need for break-in procedures required with flat tappet cams while providing superior wear resistance and valvetrain stability.

Ideal for use with stock or aftermarket cylinder heads, this cam pairs well with intake and exhaust modifications. Recommended converter stall speed: 2,400-2,800 RPM for automatic transmissions. Rear gear ratio of 3.55:1 or higher recommended for optimal performance.

Thumpr

this is my new home... very cool site, beat summit and jegs by $20 to $30

Great customer service. Fast order processing. Hassle free transaction.

Very fast shipping, received it Monday when I ordered it on Thursday. Thanks!

I found my part easily (vent visors), checkout was simple, and I was notified the very next day that my item has been sent. The price (including shipping) was way lower than anywhere else online or in town.

Autoplicity is awsome!! lowest prices.. fast shipping great customer service.. this is hard to find in todays world!!

Great service and communication. Once it was shipped, I was able to track my item. Best price I could find on the internet!! Would definitely do business with anytime.

Fantastic ! Ordered a Weather Tech Cargo Liner for my 2012 Ford Explorer. Price was $60 less here than ALL other sites on web. I was skeptical that this was going to be a counterfeit -- as the price was too good to be true. I was extremely happy to receive the genuine product as I expected in less than a week -- and for $60 less than the competitors ! GREAT VALUE and great service ! I will definitely be back !!

great ! except i signed up for 20% discount and wasn't applied. that sucks.
