The trans will be a 400 with a reverse manual valve body and a brake..nothing too fancy. The converter is an $800 (ouch) ATI blown/fuel converter spec'ed by Bill Anderson (Anderson Performance, Baltimore, MD); it's in the garage, I'll remember to take some pictures soon, hopefully.
I am hoping that Bill's experience with similar combinations will help me avoid the converter swaps that most people seem to go through with these high HP turbo cars. We'll see...
