How do I decipher the engine code on my 360/727

The engine date of production is cast onto the passenger side. Attached is a pic of my 360 block with a circle around the date. As for the trans. you need to look on the drivers side right above the pan rail. There'll be a set of #'s starting out with PK then a 7 digit # following. Here's a link to a website with those #'s so you can see what year it is
