Product Details

The COMP Cams 12-304-4 is a computer-controlled hydraulic flat tappet camshaft specifically designed for Chevrolet small block engines equipped with factory electronic fuel injection and computer control systems. This camshaft delivers 201 degrees of intake duration and 206 degrees of exhaust duration at .050" lift, providing a smooth idle quality while maintaining compatibility with stock computer programming and emissions equipment.

Key Features:

  • Hydraulic flat tappet design for quiet operation and low maintenance
  • 201°/206° duration at .050" lift for improved mid-range torque
  • Computer-controlled profile maintains stock ECU compatibility
  • Engineered for fuel-injected small block Chevrolet engines
  • Retains stock driveability and emissions compliance
  • Ideal upgrade for street-driven vehicles seeking performance gains without sacrificing reliability

This camshaft is an excellent choice for enthusiasts looking to enhance their computer-controlled small block Chevy's performance while maintaining factory-like drivability, passing emissions testing, and preserving compatibility with stock engine management systems. The conservative duration specifications ensure a stable idle vacuum for power brake operation and prevent check engine lights.
