Product Details

The COMP Cams CL51-233-4 Magnum camshaft and lifter kit delivers excellent mid-range torque and horsepower gains for Pontiac 265-455 cubic inch V8 engines.

  • Lift: .447"/.447" valve lift with 1.5:1 rocker ratio
  • Lobe Separation Angle: 110°
  • Hydraulic flat tappet design for reliable street performance
  • RPM Range: 1500-5500 RPM
  • Designed specifically for Pontiac 265, 301, 326, 350, 389, 400, 421, 428, and 455 engines

Complete Kit Includes:

  • Magnum series hydraulic flat tappet camshaft
  • 16 hydraulic flat tappet lifters

This camshaft provides a smooth idle with minimal lope, excellent street manners, and strong acceleration characteristics. The conservative duration and lift make it compatible with stock valve springs, pistons, and torque converters, while still delivering noticeable performance improvements over factory camshafts. Perfect for engine rebuilds or performance upgrades on classic Pontiac muscle cars and hot rods.
