the T56 drivetrain’s in SS and WS6’s are no different then the Formula/firehawk/trans am/ Z28 T56 cars.
also,for high HP F-bodys (1000rwhp) they take a stock T56 tranny and put in the viper shaft and something from the Cobra T56. I dont know off the top of my head what the parts are, but I read a big article on them from a company that makes them a while ago…I will see if I can find it
