Why not use the '93 Lt1 T56 trans?
I am seriously considering a swap from my auto trans to a T56. I've been doing research and I know that the '93 is not preferred due to the .62 overdrive vs. the .50 in a '94-'97 T56 (the .62 is still better than the overdrive in my 700R4). I also like the lower first gear ratio in the '93. Other than the gear ratios, why not use the '93 T56?
The reason I ask is because a brand new '93 Tremec T56 (10236021) goes for ~$1700 where a new '94-'97 Tremec T56 (12558016) goes for ~$2900.
What makes the '94-'97 T56 worth $1200 more? Experts, please!

You already posted the difference, its in the gearing, and i believe the gearing was the main factor in the 94-97 one having a higher torque capacity.

Im kicking myself in the *** right now. I just found a 95 lt1 T56 for 2500$ with 80k...damage to the front end. OMG I wish I would have bought that instead of my new motor...not only would I have a nice motor but id have a t56, better rear, and all the 4th gen interior i could handle!!!

IIRC, the '93 T56 also had a 2.95 1st gear. I know for a fact the '94-'97 T56s had a 2.66 first gear. This is what dictated the torque rating (from my understanding).

To me its if it can handle a LT1 and then some. Then it can handle a 3rd gen motor O_o I got the 94+ one though cause thats the one that I found for a good price.
