Where is the VIN on a 273 motor?

Hello,
I hope someone can give me an answer to this.
Where will I find the VIN stamp on a 273 motor?
Actually if someone has a picture showing me where it is that would be great.
I have Googled this but all I have come up with is the location of the casting number.
If you are wondering it is in a 69 Dodge Dart, which is a 68 build. It is supposed to be the original motor.
