Identifing a 727?

So I'm doing manual swap in my uncles 1970 Cuda and have pulled a working 727 out from behind the hemi.

The hemi and trans are not original to the car but the 727 does have a VIN stamp on it. I know the trans is a 69 case that shows it came behind a 383 or 440, just wondering if the vin can tell me what it came out of and possibly make it's way back to that car.

The hemi has no VIN stamp and we believe it was a over the counter purchase back in the day. 20221016_134058.jpg
