If that's the date code by where it says dist rotation it's 1-21-71 or 12-1-71. Don't know which way to read it. just has numbers 1 2 1 7 1. Maybe I'm off base there too. I'm a body guy and don't know the motor coding. Maybe someone could educate me.
 
Must be 1-21-71 because the casting number is for a 71.

12-1-71 would have been well into the 72 model year (different casting number).
 
This would be considered a later intake. spring of 71. No difference in flow from the early ones just some minor casting changes. Woody's a good guy!! GLWS

OK. So comparing it to the pics EL5DEMON34O supplied it's definitely a spring 71 manifold. So it's a 1-21-71 date code then??
