Product Details

The COMP Cams K42-308-4 Magnum hydraulic flat tappet camshaft kit delivers a complete valve train upgrade for Oldsmobile 260-455 cubic inch V8 engines. This comprehensive K-Kit provides everything needed for a professional camshaft installation in one convenient package.

Camshaft Specifications:

  • Duration: 224°/224° intake and exhaust (advertised duration)
  • Lift: .454"/.454" intake and exhaust with 1.6:1 rocker ratio
  • Lobe Separation Angle: 110°
  • Recommended RPM Range: 1,500-5,500 RPM
  • Hydraulic flat tappet design for smooth, reliable operation

Complete Kit Includes:

  • Magnum series hydraulic flat tappet camshaft
  • Hydraulic lifter set (16 pieces)
  • High-performance valve springs
  • Steel retainers
  • Valve locks (keepers)
  • Valve stem seals
  • Timing chain and gear set
  • Assembly lube for proper break-in
  • Installation instructions and decals

This camshaft profile is ideal for street performance applications, providing improved throttle response and increased power throughout the mid-range while maintaining good vacuum for power brakes and automatic transmissions. The moderate duration and lift specifications make it suitable for engines with stock or mildly modified cylinder heads and intake manifolds.
