The last year of the Speed a Motive was 2002 - In August he runs at first with a wing which breaked the streamliner, he went 396 mph. After this run, Al said at starting line that this one would be his last ever with the streamliner, I talked to him and at last he said to, after a talk with Jane, that I caught him into another run, without the wing and he went over 400 mph as final speed.
But at last Al retired from the retire again and went back to the salt in October 2002 to set another FIA record - this time a class which would be B under SCTA regulations. The record was 405 mph, but on the first run he was 432 mph on final speed.
If it was in August than it was one of the earlier under 400 runs.
Hope this helps.
