Anyone running overdrive transmission?

I've had my 200R4 in my Dart for four years. I love it. No big hassles on install, good low end power, and a .67 overdrive. I count this as the best money I have spent on this car. And, I spent a ton of money on this car. I can drive 80 mph at 2800 rpm now. And i have had it up to 145 mph with more to give before the steering and suspension scared the crap out of me and I had to slow down. I had to choose between GV and 200R4 and I am happy with my choice. Here is the thread to my install.
