Product Details

The COMP Cams CL31-331-4 Magnum/Drag Race camshaft and lifter kit delivers aggressive performance for small block Ford 221-302 engines. This hydraulic flat tappet camshaft features 253 degrees of advertised duration on both intake and exhaust, making it ideal for drag race and high-performance street applications seeking maximum horsepower and torque in the upper RPM range.

Key Specifications:

  • Advertised Duration: 253°/253° (Intake/Exhaust)
  • Hydraulic flat tappet design for reliable operation
  • Optimized for Ford 221-302 small block engines
  • Magnum profile designed for drag race and aggressive street performance
  • Requires higher stall converter and performance valve springs

Complete Kit Includes:

  • Camshaft
  • Hydraulic flat tappet lifters (16)
  • Assembly lube
  • COMP Cams decals
  • Installation instructions

This cam kit is designed for modified engines with upgraded components and is best suited for race applications or dedicated performance vehicles. The aggressive profile will produce a noticeable lope at idle and requires supporting modifications including performance valve springs, higher stall torque converter (2,500+ RPM recommended), and rear gearing in the 3.73-4.56 range for optimal performance.

They were Very quick and i was very happy with the service i got!! 9-10*

Only place I found that had the product I needed. Extremely satisfied!

Ordered a CAI kit and Autoplicity had the lowest price. They're website didn't correctly match my vehicle to the product and it took a few days to ship. They're support was friendly and quick when I emailed them about the delay.

This is the easiest purchase I ever made. The visor is great and installation was a breeze. The service by Autoplicity was A-1. Shipping was better than standard. Will buy from them again.
