I may as well be the first to complain about bd! I have the "heavy" converter. Should hold 400+hp. I hate the thing and am looking for anybody that I can to hang it onto. It can't hold much more than 400hp, horrible low stall speed, and lockup works sometimes, and sometimes not. I don't know anything about the rest of their trans parts but if they don't work any better than my converter, I'd say stay away. But this is just my experience.
