I have newer 225 in a 67 Plymouth I recently purchased and trying to figure out when the engine was produced. I read what I could on date codes and was able to match the head # 4104362 to a 1979-80 but also want to confirm the age of the block I found a number on the right side of the block which shows the engine size but not sure what the rest of the numbers mean
0 225 R 822
also on the left side is F 530-12
here is a photos of the numbers

It's a 1980 passenger car engine made on August 22, 1980.

Too many people who were born on third base actually believe they've hit a triple.
