The COMP Cams Magnum 32-239-4 is a high-performance solid flat tappet camshaft designed specifically for Ford 351 Cleveland, 351 Modified, and 400 Modified engines. This camshaft features an aggressive 248/248 degree advertised duration profile that delivers strong mid-range to upper RPM performance, making it ideal for street/strip applications and performance street builds.

Key Specifications:

  • Advertised Duration: 248°/248° (intake/exhaust)
  • Duration at .050": Approximately 208°/208°
  • Valve Lift: .488"/.488" (with 1.6:1 rocker ratio)
  • Lobe Separation Angle: 110°
  • Solid (mechanical) flat tappet design
  • Ground on COMP Cams premium core billet

Performance Characteristics:

  • Power range: 1,500-6,000 RPM
