Product Details

The COMP Cams SK12-460-8 Magnum hydraulic roller camshaft SK-Kit delivers aggressive street/strip performance for Chevrolet small block engines. This comprehensive small kit features the popular 304HR grind with 244/244 duration at .050" lift, providing an impressive .600"/.600" valve lift with factory rocker arms and a tight 110-degree lobe separation angle for maximum power delivery.

Performance Specifications:

  • Advertised Duration: 304°/304° intake and exhaust
  • Duration at .050" Lift: 244°/244° intake and exhaust
  • Valve Lift: .600"/.600" (with factory 1.5 rocker ratio)
  • Lobe Separation Angle: 110°
  • Optimal RPM Range: 3,000-6,500 RPM
  • Hydraulic roller design for reduced friction and increased durability

SK-Kit Includes:

  • Magnum 304HR hydraulic roller camshaft
  • Hydraulic roller lifters (16)
  • Double roller timing chain set
  • COMP Cams assembly lube
  • Installation instructions and decals

Application: Designed as a retrofit kit for Chevrolet Gen 1 small block engines 262-400 cubic inches (1955-1998) that were originally equipped with flat tappet camshafts. This includes 262, 265, 267, 283, 302, 305, 307, 327, 350, and 400 engines. Does not fit LT1/LT4 engines or LS-based engines.

Recommended Combination: This aggressive camshaft profile works best with a high-stall torque converter (3,000+ RPM), rear gear ratios of 3.90:1 or lower, aftermarket intake manifold, and headers. Expect a very rough, lopey idle characteristic. Requires upgraded valve springs (not included in SK-Kit). Not street legal in California (racing/off-road use only).

The COMP Cams Magnum series is constructed from austempered ductile iron for superior strength and wear resistance. This kit provides everything needed to upgrade your flat tappet engine to modern hydraulic roller technology, delivering significant power gains throughout the mid to upper RPM range while maintaining excellent durability for street/strip applications.
