Torque Converter for 6.1 Hemi 904 Trans

Hi,
I am starting the process of installing a 2006 6.1L hemi into my 1973 Dodge Dart Swinger and I am planning on using my existing 904 transmission that was previously rebuilt for use with the built 360 I had in the car. I have not been able to find much information on the correct torque converter to use in this setup. I would appreciate any advice. Thanks
