Product Details

The COMP Cams Magnum 10-204-4 is a hydraulic flat tappet camshaft specifically engineered for AMC V8 engines ranging from 290 to 401 cubic inches. This camshaft features a symmetric 230/230 degree duration profile that delivers excellent mid-range torque and improved throttle response while maintaining good vacuum for power brakes and accessories.

Camshaft Specifications:

  • Advertised Duration: 280°/280° intake and exhaust
  • Duration at .050": 230°/230° intake and exhaust
  • Valve Lift: .462"/.462" (with 1.6:1 rocker ratio)
  • Lobe Separation Angle: 110°
  • Recommended RPM Range: 1,500-5,500 RPM
  • Hydraulic flat tappet design for quiet, reliable operation

This camshaft is ideal for street performance applications in classic AMC vehicles including Javelins, AMXs, and Jeeps. The balanced duration profile provides a noticeable performance increase over stock while remaining emissions-friendly and compatible with stock torque converters and rear gear ratios. Requires compatible hydraulic flat tappet lifters, pushrods, and valve springs (sold separately).
