The engine block casting date, which I located on the pass side just above and in front of the starter reads - A 30 9 ( January 30, 1969 ), best as I could make out. Very rough casting and time hasn't been kind to it. I used a piece of aluminum to capture the impression after trying a pencil to shadow transfer onto paper. Between the two images I could make out the date. So, looks like it was cast just a few days after the heads. The heads and block castings seam arguably close enough to be paired together upon assembly. Anyone out there with information on Tonowanda's assembly procedures, your input would be very much appreciated.
