Product Details

The COMP Cams 33-781-11 Magnum solid roller camshaft is engineered specifically for Ford FE-series big block engines (352, 360, 390, 406, 410, 427, and 428 cubic inch). This high-performance camshaft features aggressive 243/243 duration specs designed to deliver substantial power gains in street/strip applications with excellent throttle response.

Key Specifications:

  • Advertised Duration: 243° intake / 243° exhaust
  • Lift: Optimized for solid roller lifter applications
  • Lobe Separation Angle: Engineered for broad power curve
  • Camshaft Type: Solid roller design for maximum performance and durability
  • Application: Ford FE-series engines (352-428 ci)

Performance Features:

  • Solid roller design eliminates lifter friction for increased horsepower
  • Aggressive lobe profiles provide exceptional valve control at high RPM
  • Magnum series design optimized for street/strip performance
  • Requires solid roller lifters, hardened pushrods, and upgraded valve springs (sold separately)
  • Ideal for engines with aftermarket heads, headers, and performance intake manifolds

This camshaft requires proper valvetrain components including solid roller lifters, appropriate valve springs with correct seat pressure and coil bind clearance, hardened pushrods, and proper break-in procedures. Professional installation and valve train setup is strongly recommended to achieve optimal performance and reliability.
