My guess is that the 7115 cranks were probably used with the heavier open chamber 12.5:1 domed pistons for the L88 and ZL1 since the counterweights are slightly wider for balancing purposes. The 396 and 427 11:1 closed chamber pistons were lighter and worked with the narrower counterweighted 6223 crank.
