224 PredatorThe 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.
