Product Details

The COMP Cams Mutha' Thumpr K20-601-4 is a complete camshaft kit engineered for Chrysler small block 273-360 cubic inch V8 engines. This aggressive hydraulic flat tappet camshaft delivers the signature Thumpr lope and strong mid-range performance, making it ideal for street rods, muscle cars, and performance street machines looking for that classic high-performance sound and feel.

Camshaft Specifications:

  • Duration at 0.050": 235°/249° (Intake/Exhaust)
  • Advertised Duration: 279°/297°
  • Valve Lift: 0.501"/0.520" (with 1.5 rocker ratio)
  • Lobe Separation Angle: 107°
  • Hydraulic flat tappet design for reliable street use
  • Choppy idle with aggressive exhaust note

Complete K-Kit Includes:

  • Mutha' Thumpr hydraulic flat tappet camshaft
  • Hydraulic lifter set (16 lifters)
  • High-performance valve springs
  • Spring retainers
  • Valve locks (keepers)
  • Valve stem seals
  • Timing chain set
  • Assembly lube
  • Installation instructions and decals

This kit provides everything needed for a complete camshaft upgrade in one box. The Mutha' Thumpr profile is designed to work with stock torque converters and rear gears, though a 2,200+ stall converter and 3.55 or higher rear gears are recommended for optimal performance. Requires valve spring pocket machining and proper break-in procedures for flat tappet camshafts.

Great prices

As described. Prompt delivery.

I received original factory parts and paid less than the bobo brand carquest, O'Reilly, autozone, and advanced auto sell. Being factory original everything simply unplugged and went Right back together! Very pleased!!! Not to mention I saved $200 on just the one item!! Yea I'll be a regular customer from now on thanks guys.

So far so good

Lowest price and super fast delivery Autoplicity ROCKS!!

Quick Service and great pricing!

I have looked for this product many times but was disappointed<br>in the price. could not beleive the price at Autoplicity. thank <br>you very much keep up good work Ray

I ordered the HuskyLiners 98891 Floor Liners for my 2012 Hyundai Elantra on 5/29, received them 5/31. Order #15417. Apparently they have warehouses all over the country to ensure quick delivery. They had the best price on the net. Item arrived in perfect condition. <br><br>Their website needs a little work because I found the item thru Google and not directly from their website. You also can't edit your cart unless you register first which was annoying. Items could use product descriptions - you have to get info from the manufacturer's site. The real-time inventory was a plus.<br><br>Deducted a star because their website needs work.

Bought some wire looms for my Chevy from them. Great price, service, and shipping speed!

Product delivered as expected within 4 days. Lowest price on the web. No complaints.

We looked a lot of places online for the steering stabilizer for our vehicle. We priced and looked to find out who had the best product and fastest shipping. We were so glad that Autoplicity was able to have just what we needed. We highly recommend that you visit autopicity.com for all you vehicle needs and we thank Autoplicity for their expediency in getting us our stabilizer.

Good prices, fast shipping, A+

After checking amazon, ebay, various other general and specialty online parts suppliers and local brick and mortar supply houses, Autoplicity's was hands down the best overall (price + shipping) price for the product.

Best price I could find on the web and great easy to use website. Fast shipping, I am overall very satisfied thanks Autoplocity!
