Product Details

The COMP Cams CL21-242-4 Magnum hydraulic flat tappet camshaft and lifter kit is engineered for Chrysler big block 383-440 cubic inch engines seeking improved performance across the RPM range. This complete kit delivers a balanced combination of low-end torque and mid-range power, making it ideal for street performance applications and mild street/strip builds.

Camshaft Specifications:

  • Advertised Duration: 244° intake / 244° exhaust
  • Duration at .050": 224° intake / 224° exhaust
  • Valve Lift: .462" intake / .462" exhaust (with 1.5:1 rocker ratio)
  • Lobe Separation Angle: 110°
  • Recommended RPM Range: 1,500-5,200 RPM
  • Hydraulic flat tappet design for reliable street performance

Complete Kit Includes:

  • Hydraulic flat tappet camshaft
  • Assembly lube for proper break-in
  • Installation instructions
  • COMP Cams decals

This camshaft profile provides excellent drivability with a mild to moderate idle quality, making it suitable for vehicles with stock or mildly modified engines. It works well with stock torque converters (2,000-2,400 stall) and factory compression ratios. The hydraulic design requires no valve lash adjustment, simplifying maintenance for street-driven applications.

Designed specifically for Chrysler big block B and RB engines including 383, 400, 413, 426 wedge, and 440 applications. May require upgraded valve springs depending on existing components—verify spring specifications before installation.
