what is a good torque convertor

thanks for the info. I am going to call these guys and see what is going on. I never had any idea that a custom one was better than one off the shelf. I believe I either bought this one from Hughes or directly from Summit. I will have to go through the papers and see. I have been tied up with my wifes shoulder surgery for the past 2 weeks and have not had time to do much. I have to see who will put this in for me also. I don't believe I am up to it yet from my open heart surgery. But will do if I have to. Thanks for the info. I have learned something.
