Product Details

The COMP Cams Mutha' Thumpr CL31-602-5 is a high-performance hydraulic flat tappet camshaft and lifter kit engineered specifically for Ford small block 221-302 cubic inch engines.

  • Duration at .050": 207°/221°
  • Valve Lift: .444"/.465" (with 1.6 rocker ratio)
  • Lobe Separation Angle: 112°
  • Hydraulic flat tappet design for reliable street performance
  • Optimized for engines with 9.0:1 to 10.5:1 compression ratio

The Mutha' Thumpr series features increased exhaust duration and aggressive lobe profiles that produce a pronounced performance exhaust note and strong mid-range power. This camshaft requires aftermarket valve springs with higher seat pressure and works best with headers and a performance exhaust system. Ideal for street rods, muscle cars, and weekend cruisers where aggressive sound and strong throttle response are priorities.

ordered 4 cans to prime/paint/clear coat some rims. paint came in 2-3 days (incredibly fast). They forgot a can, i emailed and got a reply within 20 minutes, and the can was on my doorstep the next day. im very impressed

Great

Fantastic service and fast shipping! Lowest price on the net for the CAI that I bought!<br><br>This is my new "Go To" website for parts.<br><br>Thanks!

I would def order again from them great price and fast shipping.

Great price, fast shipping, excellent customer service. I will definitely do business with them in the future.

No problems ordering a leak down tester from Autoplicity which had the lowest price and reasonable shipping charges. The item was well packaged and I would buy from them again.

Autoplicity had the best price on the Wiseco pistons I needed anywhere. Took a little longer to arrive than I expected but apparently that was due to the pistons being shipped directly from the factory. Otherwise a very good experience overall.
