Mike, Wow! Nice matching set of everything! Parts and tags!
I'd move the tag to the engine..... detail thing..... Carefully flatten it out using a piece of nylon block to tap with.....or hardwood.....put it on similar spot as where you found it if possible.
Dan had the details right re: squarebore and regular Autolite...
You have a Feb of 71 engine, perhaps Feb 12th. K613J= M-code in VIN
Carb is Torino-Mustang/Cougar Manual Trans with "M" engine code in VIN. The suffix on the carb "EA" will give details such as manual or auto trans in the Master Parts Catalog, and the number base part number D1OF indicates bodystyle that the part was originally intended... (O=Fairlane/Torino bodystyle Mustang/Cougar would be D1ZF)
Carb tag has more info on bottom row, B=design change 1=71 D= April and 19=day, so April 19, 71 was day carb was built.
In this case, it looks like carb was assembled a few months later than the engine.......possible I guess! Since these were warehouse engines.......could have more variance in dates than production line engines.......anyone's guess.
What Ken has on his tag, is a D2ZF-AA which is for a "351CJ" in 72. His tag -AA tells us that it is for F-code cars (Mustang/Cougar) with Manual Trans EXCEPT CA! His tag looks to have been made in December of 1971 by the 1 and M in the lower row, which would be proper for a 72 car....(which started production back in August to Sept for new car sales!
There were D1ZF carbs in 71, but they were the Boss carbs in Mustangs.
The Motorcraft name replaces Autolite somewhere in late 71, so you could see either name on a mid 71-ish production piece. Late 70 and early 71 would tend to see more Autolite bits, and later 71 the Motorcraft name would start appearing. It's a Ford thing.....
Now ya knows! Steve

Guys,
Doing a garage cleanup and stumbled across Lori's original 1971 Pantera intake and carb.
I always believed that Panteras came with spread-bore intakes and Autolite 4300D carbs. But this intake is a square bore with matching Autolite square bird carb.

Carb ID tag:
Engine ID tag on intake:
Intake casting number:
So what do you smart people think of this? Steve?
