400GTO, What does the convertor stall to now? At 1900 it sounded like you had a stock convertor, but with the increased power it might go somewhat higher. Be sure to check where your total timing is at about 3000 rpm, w/o the vacuum advance hooked up. With pump gas you don't want any more than about 36 degrees, but more than likely, less.
