Bow Tie Power

I just bought a 1997 Camaro Z28 without a motor. I'm trying to make sure the transmission I have is a T-56 but I cannot confirm it, even after looking all over the internet. I saw 2 different casting numbers. One is right under the Borg Warner Automotive engraving and the other is in a random spot on the other side. The one under the BWA engraving shows: 13-86-066-904-(F). The one on the other side is close but instead it shows: 13-86-065-902. The green aluminum tag shows: 2558016 C2171 3-86-016 D 15892.
The 3 right before -86-016 could possibly be an 8. (Its very difficult to tell.) Any help would be greatly appreciated.

Post a picture of it. You can easily tell if its a T-56. Im going to guess its a T56

the 1386-065-902 is a T56 case casting number . The green tag indicates an F-car application ( 1386-016 MODEL)....pre LS1...97 or older

The rest of the tag code:
2558016= GM part number
c2171= build code : march 21, '97 , 1st shift
15892= serial number

BTW this is a Borg-Warner produced box.

Weren't most of them BW?

I think Tremec bought the design/rights from BW (or took them over completely??) somewhere around 1999, but I'm not sure on that one.

apparently so. LS1 cars had a tremec and LT1s had a BW it looks like
