Hey do u know if anyone ever advanced the timing on the car? Its a popular thing to do with the mustang to get a few extra horses out of the motor. If the timing is advanced too much it would lead to pinging. Also when timing is advanced higher octane fuel is required to prevent pinging, which kinda sounds like ur situation. Well since ur dad owned the car, see if he knows anyhting about a timing adjustment.
