I had a guy named Pat rebuild my 426 wedge back in the 80's. Don't remember his last name but his business name was Pat's Trans Doc in Post Falls. He was a Hemi guy, had a Hemi b body race car and a couple of early b body cars. One MW and I think the other was Hemi. I think it is the same Pat but I'm not sure. He left Post Falls so maybe he went over to the Seattle area. A-1 Performance Transmission is in Vancouver, WA these days. They left SoCal and moved north.
