T-56 Transmission Install Thread
Viper/LS have same input shaft length. LT1's dont have the front adapter plate on the trans, and that is where the difference is. I wouldn't use an LT1 version since they were not designed to take more than about 300 ft/lbs.
That's not entirely correct as you're speaking of the early version and that's understandable coming from a Moparian...
