Product Details

The COMP Cams K31-331-4 Magnum/Drag Race K-Kit is a complete high-performance camshaft package designed for Ford small block 221-302 cubic inch V8 engines. This hydraulic flat tappet camshaft features aggressive 253/253 degree duration specifications, making it ideal for drag racing and high-performance street applications seeking maximum power gains.

Complete K-Kit Includes:

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

This all-in-one kit eliminates the guesswork by providing every component needed for a complete camshaft installation. The 253/253 duration profile delivers strong mid-range to top-end power, making it well-suited for engines with aftermarket cylinder heads, headers, and higher compression ratios. The hydraulic flat tappet design offers excellent performance while maintaining simpler maintenance requirements compared to solid lifter configurations.

Application: Ford small block V8 engines (221, 260, 289, 302 cubic inch)
