Though Frank Lockhart had been dead for a year, cars he engineered won the top two spots at the 1929 Indianapolis 500. When his estate was settled, the two Millers he had bought and modified himself were sold to separate buyers, M.A. Yagle and Alden Sampson. Ray Keech drove for Yagle and and Louis Meyer for Sampson.

Meyer had the lead late in the race but an oil leak sent him to the pits long enough for Keech to pass him by and get a lead too big for Meyer to overcome in the remaining laps.

Duesenberg driver Bill Spence was killed early in the race, and 16 days later Keech also would be dead after a wreck in Pennsylvania.
