Product Details

The COMP Cams Big Mutha' Thumpr CL96-602-5 is a complete camshaft and lifter kit designed specifically for Buick V8 engines including 400, 430, and 455 cubic inch applications. This hydraulic flat tappet cam delivers an aggressive 243/257 duration split that produces the signature Thumpr lop and aggressive sound while maintaining good street manners and vacuum for power brakes.

Key Specifications:

  • Advertised Duration: 243° intake / 257° exhaust
  • Duration at .050": 224° intake / 234° exhaust
  • Valve Lift: .491" intake / .491" exhaust (with 1.5:1 rocker ratio)
  • Lobe Separation Angle: 107°
  • Hydraulic flat tappet design for reliable operation
  • Compatible with Buick 400, 430, and 455 V8 engines

Complete Kit Includes:

  • High-performance camshaft
  • Hydraulic flat tappet lifters (full set)
  • Assembly lubricant for proper break-in
  • Installation instructions
  • COMP Cams decals

This camshaft is ideal for street machines and muscle car builds looking for maximum sound and attitude with a choppy idle. The aggressive exhaust lobe profile creates strong mid-range torque while the tighter intake lobe maintains drivability. Best suited for engines with 9.0:1 or higher compression, aftermarket exhaust systems, and upgraded valve springs. Produces optimal power between 1,800-5,800 RPM.

Great prices.

Quick and easy. Just hope it fits my car.

Just order the 1108 turn over ball for 2010 Super Duty and received it within (5) days. Just can't wait to put it on and start pulling the trailer with my new diessel.

Just recieved my order and the pit jug and spout were perfect. The shipping was very fast and it was by far the best price I could get on these products. Autoplicity is great.

Lowest prices around the web and excellent customer service. The only real issue was the wait between placing the order and when it was shipped. Took 4 days but I chalk that up to the large amount of business they due to their prices being so competitive. For the lowest prices that I've seen I didn't mind waiting a bit longer!

Great online shopping. Easy to navigate and order, telling you just how many product are left so you know if you need to buy now. fast processing and shipping too
