Product Details

The COMP Cams K33-238-4 Xtreme Energy K-Kit is a complete camshaft upgrade package designed specifically for Ford FE-series big block engines (352, 360, 390, 406, 410, 427, and 428 cubic inch). This comprehensive kit delivers improved performance with a 218/224 duration profile that provides excellent mid-range torque and increased horsepower while maintaining good street manners and reliability.

Camshaft Specifications:

  • Advertised Duration: 268°/274° Intake/Exhaust
  • Duration at .050": 218°/224° Intake/Exhaust
  • Valve Lift: .480"/.480" Intake/Exhaust (with 1.73:1 rocker ratio)
  • Lobe Separation Angle: 110°
  • Hydraulic flat tappet design for durability and low maintenance

Complete K-Kit Includes:

  • Xtreme Energy camshaft
  • Hydraulic flat tappet lifters (16)
  • High-performance valve springs
  • Steel retainers
  • Valve locks (keepers)
  • Valve stem seals
  • Timing chain set
  • Assembly lube
  • Installation instructions and COMP Cams decals

This Xtreme Energy cam profile is ideal for street/strip applications, muscle car restorations, and performance street builds. It works well with stock or mildly modified engines and delivers a noticeable performance gain with a smooth idle quality. The kit includes everything needed for a complete valvetrain upgrade, eliminating the guesswork of component matching and ensuring all parts work together for optimal performance.

Recommended Application: Street performance, muscle car builds, mild street/strip use. Works with stock torque converters (2,000+ stall recommended for automatics) and stock to mildly modified cylinder heads. Requires 9.0:1 or higher compression ratio for best results.
