Product Details

The COMP Cams Thumpr CL32-600-5 is a complete camshaft and lifter kit engineered specifically for Ford 351 Cleveland, 351 Modified, and 400 Modified engines. This hydraulic flat tappet camshaft delivers an aggressive 226/241 duration profile that produces the signature Thumpr lope at idle while providing strong mid-range torque and horsepower gains.

Key Specifications:

  • Advertised Duration: 268°/280° intake/exhaust
  • Duration at .050": 226°/241° intake/exhaust
  • Valve Lift: .501"/.510" intake/exhaust (with 1.73:1 rocker ratio)
  • Lobe Separation Angle: 107°
  • Hydraulic flat tappet design for reliable operation

The Thumpr series is designed for street performance enthusiasts who want that classic hot rod idle sound combined with excellent throttle response and street manners. This cam works best with 9.0:1 to 9.5:1 compression ratios, performance intake manifolds, headers, and 2,000-5,800 RPM operating range. Requires aftermarket valve springs and may require additional valvetrain components for proper installation.

Faster shipping than I expected. Easy order process. The ignition switch was my problem and Autoplicity part was exactly what I needed at a price better than anyone else had, with shipping included. I will definitely look to them again when I need any more parts for my Monte Carlo SS.<br>Only slight negative would be it took a few days to get an email with tracking number so I would know when my part would come. But once I got it, found it was coming sooner than I originally thought, which was great.

Great price and fast shipping. Good experience!

Great service. fast shiping!

Very fast shipping and bottom line prices for every part. Awesome website. Will be telling all my friends about and using again for sure!!

So I have an old car. It's and 83, seven years older than me. I'm also a student so I don't have much money and need to make as many repairs myself to save money. I go out to the local pep boys and auto zone to to try to find a repair manual that is for my old model but it's not available. I check online and there are very few copies on line. Autoplicity had the right manual at the lowest price by a good margin. <br><br>TLDR; Autoplicity has EVERYTHING and at a cheaper price

Prompt order processing and shipping, the item I received came in good condition and I am eager to get it installed on my car. Over the phone customer support was prompt and polite, I would order from them again.

The magnaflow kit that I ordered was about $100 cheaper than any other site I could find. Shipping was fast, and relatively cheap too.
