    Suburban + Mileage? Similar to Military + Intelligence or Jumbo + Shrimp!
    More seriously, my 91 350/tb1/3:42 almost got 16 once.. normally ran about 13+ in COS (a mile + above sea level). Have never seen that 15.89 ever again.. Now in the flatlands, and 4:10s with 16" tires... Getting around 12... near 14 on a great day & a tail wind.
    Driving (and towing?.. down to 7-ish) style can slide the numbers Up or Down!
