Re: [Amc-list] 252 six

The 195.6 OHV is indeed the "dead end" of the family. It's related to the 172.6 first made for the Nash 600 in 41. In the flatheads the bore was the same and the stroke was increased in 1/4" increments (as Ken noted below).  It was converted to OHV in 1956 by changing the casting -- there was no L-head in 56 or 57. In 57 the water pump was moved from the side od the block to the front, and in 58 when the L-head was reintroduced the front water pump was retained.
