I have a 5200 Ultimate Converter Concepts stall in my 904 and you would never know it was high stall. Lenny told me that at idle I could put it in gear, let off the brake and the car will move. He was correct, new technology is amazing
Ultimate is the best ! I have three of them : the 8 inch in the 904 in my Dart , a spare 8 inch and they redid the lockup one for the 518 in my D150 ( I picked up over a tenth in 60 ft )
