When the race returned in 1946 after the Second World War, Williams again failed to qualify.
In 1947 he qualified a Novi powered Kurtis but it was driven by Herb Ardinger, who finished 4th, completing all 200 laps.
He failed to qualify in 1949 and it was the end of his Championship car career.
Williams did not attempt to qualify for any Championship Car races other than the Indianapolis 500.
