I think I am more interested in the SRT rear end. by adding a turbo to my V8, I should be well past the torque limits of the n/a trans. The SRT trans is the same as the 722.6 that was used behind n/a MB V8's. Unfortunately, If I change trans I also have to switch to a 3.07 rear end and use the correct TCU for the trans and rear ratio. Take me off the list for the n/a rear end.
