During the 1924 Indianapolis 500 Corum, in third place, was replaced by the more well-known Joe Boyer on lap 109 on orders of the head of the team after Boyer's car developed trouble. While Corum received the prize money and was credited with the victory (later this was changed to the two drivers being co-winners), Boyer received most of the credit from the racing community. Corum qualified for the 1928 Indianapolis 500, but suffered a crash during a practice run on the morning of the race.
