After breaking down the engine, the "2" is indeed a "z" although the bottom part is fairly light. The same number was stamped at the lower right of the side plate on the block as well but not with the Z. Did not see that on my other 216 engine. In the casting itself was 11 42 which I took to be Nov. of 1942.
