Product Details

The COMP Cams 12-268-4 XE Computer Controlled camshaft is engineered specifically for small block Chevrolet engines with computer-controlled fuel injection and emissions systems. This hydraulic flat tappet camshaft delivers a significant performance upgrade while maintaining compatibility with factory EFI, oxygen sensors, and computer controls.

Camshaft Specifications:

  • Advertised Duration: 268°/280° intake/exhaust
  • Duration at .050": 224°/230° intake/exhaust
  • Valve Lift: .454"/.475" intake/exhaust (with 1.5 rocker ratio)
  • Lobe Separation Angle: 110°
  • Hydraulic flat tappet design for quiet operation and low maintenance
  • Computer-controlled profile optimized for modern EFI systems

Performance Characteristics:

  • Idle RPM range: 1,500-2,000 (smooth, street-friendly)
  • Power range: 1,500-5,500 RPM
  • Excellent torque increase throughout the powerband
  • Maintains stock-like drivability and fuel economy
  • Compatible with stock torque converters and rear gear ratios

This camshaft is ideal for street performance applications where you want noticeable power gains without sacrificing daily driveability or triggering check engine lights. The XE Computer Controlled series is specifically calibrated to work with mass airflow sensors and factory computer tuning parameters. Perfect for trucks, daily drivers, and street machines running stock or mildly modified small block Chevy engines from 262ci to 400ci.

Note: Requires compatible hydraulic flat tappet lifters, pushrods, and valve springs (sold separately). Professional installation and proper break-in procedure recommended.
