How do you tell what year a motor was made?

The first letter of the code identifies the decade (C=1960s, D=1970s, E=1980s), the second digit in the code identifies the specific year. A 1973 motor for instance would be D3, as an example.
How can you tell the difference between a 350 and a 327?
The difference in the displacement comes from the crankshaft stroke. The 327 uses a 3.25 inch stroke, where the 350 uses a longer 3.48 inch stroke(thats what makes it bigger). Depending on the year of the block, the biggest difference in the block itself is the main journal size.
