Gears or torque convertor

This is also one of the things I am doing homework on when putting my engine/transmission/rear end combo together on the Valiant I'm building. I'm not going to to go into detail on my build since this is not my thread, but to help the OP as well; Who do you guys recommend someone contact to build a custom torque converter? Please provide a link, email address, or phone number if you can.

Thanks,
Rob
