COMP Cams SK42-220-4 Xtreme Energy Camshaft SK-Kit

The COMP Cams SK42-220-4 Xtreme Energy hydraulic flat tappet camshaft kit is engineered specifically for Oldsmobile 260-455 cubic inch V8 engines. This complete SK-Kit provides everything needed for a professional camshaft installation, delivering improved performance across the RPM range with aggressive valve timing specifications of 206° intake duration and 212° exhaust duration.

Complete Kit Includes:

  • Xtreme Energy hydraulic flat tappet camshaft
  • Matching hydraulic lifters (16 pieces)
  • High-performance timing chain set
  • Assembly lube for proper break-in
  • Installation instructions
  • COMP Cams decals

Performance Features

The Xtreme Energy camshaft profile features 206° intake duration and 212° exhaust duration, designed to optimize low-to-mid range torque while providing strong top-end power. The hydraulic flat tappet design ensures quiet operation and low maintenance compared to solid lifter configurations. This kit is ideal for street performance builds, muscle car restorations, and vehicles requiring improved throttle response and power delivery.

Application

Direct fit for Oldsmobile small block and big block V8 engines ranging from 260 to 455 cubic inches. Compatible with stock valve springs and components, making it an excellent upgrade for street-driven vehicles seeking noticeable performance gains without extensive engine modifications.

Installation Notes

Use the included assembly lube on all camshaft lobes and lifter contact surfaces during installation. Follow COMP Cams break-in procedures carefully to ensure proper lifter and lobe wear patterns. Verify proper valve spring pressure and geometry for optimal performance and longevity.
