What is the code pressed/stamped into the block at the rearward of the distributor?

That is the Engine Serial Number and it should contain the cubic inches of the engine.

If you want to ID the year of the engine, we will tell/show you the location of the date casting code (I will look for a labelled photo for the locations of codes).
