Product Details

The COMP Cams Thumpr 10-600-11 is a high-performance hydraulic roller camshaft engineered specifically for AMC V8 engines from 290 to 401 cubic inches. This camshaft delivers the aggressive Thumpr sound and performance characteristics that muscle car enthusiasts demand, with excellent street manners and strong mid-range power.

Camshaft Specifications:

  • Advertised Duration: 279°/293° intake/exhaust
  • Duration at .050": 227°/241° intake/exhaust
  • Valve Lift: .477"/.480" intake/exhaust (with 1.6 rocker ratio)
  • Lobe Separation Angle: 112°
  • Hydraulic roller design for reduced friction and increased durability
  • Ideal RPM range: 1,600-5,400

Key Features:

  • Part of COMP's legendary Thumpr series known for aggressive idle and powerful sound
  • Hydraulic roller followers eliminate the need for constant valve adjustments
  • Optimized for street performance with automatic or manual transmissions
  • Compatible with stock valve springs and other factory components
  • Delivers noticeable power gains throughout the RPM range

This camshaft is designed for performance street applications and works exceptionally well in AMC-powered vehicles including Javelins, AMXs, and Jeeps. The Thumpr profile provides that classic hot-rod lope at idle while delivering strong torque and horsepower gains. Requires hydraulic roller lifters (sold separately) for proper installation.
