As a Y-Block fan I truly appreciate this website.  It is a wealth of information.  Thank you.  I have been working on a display of intake manifolds I have collected over the years.  I believe the Y-Block is one of few engines that offered various intake manifolds to support the different 2 bbl and 4 bbl carburetor configurations offered from 1954-1964.  As I began to clean the intakes, I became more interested in the information cast into each manifold.  I have had limited success obtaining information about the Date of Manufacture Code and its location on blocks, heads, and intake manifolds.  Has anything been written on the subject on this site or can you direct me to where I might find such information?  Thank you.
