CCA is a relatively recent rating system for manufacturers who are embarrassed to publish the A/H rating of their batteries. 50 years ago, nobody had even heard of CCA's. The easy way to build a high CCA battery is to use lots of very thin plates in the cells to decrease internal resistance. Those batteries shed plate material like a Persian cat sheds hair, particularly in an environment with a little vibration.
