About to buy a torque converter which would work the best?

We used to run a tight 10" Turbo Action convertor in my sons Dart behing the mild 383 it used to have. Great convertor as Turbo Action is first class stuff. It ran 12.30's with it and it drove like a stock convertor. You will like it. Now we run a Dynamic 9.5 and it also works great behind the 400. Ron
