Product Details

The COMP Cams SK11-422-8 Xtreme Energy hydraulic roller camshaft SK-Kit is engineered for Chevrolet Big Block 396-454 engines seeking aggressive performance with excellent mid-range to top-end power. This 218/224 duration camshaft delivers a noticeable performance increase with a lopey idle and strong acceleration characteristics, making it ideal for street/strip applications and performance street builds.

Kit Includes:

  • Xtreme Energy 218/224 hydraulic roller camshaft
  • Hydraulic roller lifters
  • High-performance timing chain set
  • Assembly lube for proper break-in
  • Installation instructions
  • COMP Cams decals

Camshaft Specifications:

  • Advertised Duration: 218°/224° (intake/exhaust)
  • Lift: Optimized for hydraulic roller applications
  • Lobe Separation Angle: Designed for strong mid-range torque
  • Valve train: Hydraulic roller design for reduced friction and increased durability

The Xtreme Energy camshaft line features aggressive lobe profiles that maximize performance while maintaining street manners. The hydraulic roller design provides the benefits of reduced valve train friction, improved durability, and faster valve actuation compared to flat tappet camshafts. This SK-Kit (Small Kit) provides all the essential components needed for a camshaft upgrade, though additional components such as pushrods, springs, and gaskets should be verified for your specific application.

Recommended for engines with upgraded valve springs, aftermarket cylinder heads, and performance intake/exhaust systems. Best suited for street performance vehicles, weekend cruisers, and muscle car restorations where increased power and an aggressive exhaust note are desired.
