The air velocity in the intake runners/cylinder ports will be much more important than that at the TB. Use the larger TB and see if you get gains. I suspect you will see some, though whether or not it will be enough to "feel", I don't know.
Also, you didn't mention anything about the TPS. Did you use the Mustang unit, or did the stock TPS from your SVT bolt right up?
I used the TPS from the Mustang unit. The only modifications to the TB were; 1) A little shaving off of the plastic Throttle cable holder, 2) Drilled out the hole that the Throttle cable connects to, 3) A slight bending of the metal piece which stops the TB from over opening. Other than those things it bolted up just fine. I have the pics. I just want to doctor them up with arrows so they can be clear as what to modify.
