Torque Converter

Hey guys I will be installing a New Hughes Torgue converter in my SB 408 Stroker with a 727 tranny so how much tranny fluid do I put in the converter before I install it. Some said only 4 quarts and some said to fill it up completely. I am leaning towards the 4 quarts. Thought that I would ask the professionals on here. Thanks
I always out just 1 qt in mine , just to make sure of not having a dry startup...
