CM Grind, 224cc

Description

• The CM is a mild cam for great mid-range torque and requires an upgraded spring package, billet rod, and flywheel. More duration on the intake for use with bored stock or Tillotson carb.
• The lobes are hardened for extra durability, extending the life of this cam.

The 224cc camshafts have .550" main journal sizes. The cams have been clearanced between the lobes and feature narrow lobes. These modifications allow for rod clearance due to the 58mm stroke. The compression release is also thinner to clear the 58mm crank counter weight. These camshafts work with Harbor Freight Predator 224cc and Tillotson 224cc engines.
