I'd forgotten about this one. How about this:
"Ralph DePalma drove a strictly stock 1924 Chrysler a full thousand miles while averaging 68.33 MPH in an elapsed time of 1,007 minutes and 54 seconds - actual underway time was 878 minutes, 10.8 seconds - done at Fresno, California on 17 September 1924 under American Automobile Association official supervision."
