Product Details

The COMP Cams 34-331-4 is a hydraulic flat tappet camshaft specifically designed for Ford 429 and 460 cubic inch big block engines. This Magnum/Marine profile camshaft delivers a balanced performance upgrade with 230 degrees of advertised duration on both intake and exhaust, making it ideal for marine applications and street/mild performance builds where smooth idle quality and strong low-to-mid range torque are priorities.

Key Specifications:

  • Advertised Duration: 230°/230° (intake/exhaust)
  • Camshaft Type: Hydraulic flat tappet
  • Application: Ford 429, 460 big block V8 engines
  • Profile: Magnum/Marine series
  • Idle Quality: Smooth, stock-like characteristics

Performance Characteristics:

  • Excellent low-end and midrange torque production
  • Maintains good vacuum for power brakes and accessories
  • Compatible with stock valve springs and components
  • Suitable for marine applications with reliable, proven performance
  • Works well with stock or mildly modified cylinder heads

This camshaft is an excellent choice for RV, truck, and marine engine builds where drivability and reliability are essential. The conservative duration keeps the powerband optimized for typical operating RPM ranges while providing a noticeable improvement over stock performance. Compatible with stock torque converters and rear gear ratios.
