Overdrive auto for a 383 72 Dart

Can the 200R4 be built to take the punishment The 727 will? When were done we are hoping to be around 600Hp and 500/550 ft lbs I have no issues running a adapter as long as it will take the abuse when it's given and if this is a good fit does anyone have any good links or contacts?

Art Carr has a 2004r that will take that kind of horsepower for a couple of grand.
There is an excellent thread on this board on the installation of a th2004r into a Cuda. It is under will a stock floor shift fit a 2004r (or something like that) Lots of photos for you to look at, and see what you'll get your self into.
Pat Storey at SMR transmissions has a bolt on overdrive adapter you might want to also think about. No cutting of floor boards, no adapter plates, etc. associated with the 2004r change over.
