The CL3-B is buffed adding smoothness to the lobes. The CL3 utilizes the -5 duration check, in the AKRA rule package, by allowing a softer ramp rate on the nose of the cam. This design has shown gains in the 6200+ RPM range with minimal loss in peak horsepower. The DynoCams CL3 is legal for the current profile rules for stock classes. The lobes are hardened for extra durability, extending the life of this cam.
