Default 93 LT1 vs 94-97 LT1 T56 difference?

I picked up an LT1 t56 that i plan on converting to mate to a vortec 5.3

I'm not sure if the tranny is from a 93 or 94 firebird formula. could someone tell me some differences in the transmissions and what i could look for to verify if my trans is a 94 and will work for conversion. I've spent hours trying to look up information but have been unsuccessful so I thought id ask.

Put in first.

9 turns of the input turns the output 3 times or less, it's one of the 93 ratios.

3.38 turns, it is 94-up.
