Default Engine Markings

Greetings,
I have been working on cleaning the engine of my 67 Coupe, and under the grease and grime I came across what looks to be a date written in yellow paint on both sides of the lower block. It looks to be either 3A14 or 314. If it is in fact a date, the date would correspond with my serial number and tank sticker. Per the previous owner the engine had never been taken out! I didn't see anything on this in a search, so I thought I would post a picture of it and get your thoughts

Thanks,
Pat

It is an "HE" block but why would it be inverted and written as "3H" on the side?

HE was probably written on there during assembly. Block was upside down at the time it was written ! Good find. Always neat to see these markings that have survived.

The first station on the engine assembly line at Flint V-8 (and at Tonawanda) was an air-gaging machine that precisely measured the bore diameters; the block was upside-down in that station, and the suffix code was written on the side of the block so the assemblers further down the line would know what innards (cam, crank, rod/piston assemblies, lifters, heads, etc.) that particular engine required. It also showed the pad-stamp operator which suffix gang-holder to use after the heads went on.
