The 1952 Indianapolis 500 starting field consisted mainly of specially designed Indy roadsters with few dirt champ cars and one formula one-based Ferrari. J.C Agajanian, famous American racing promoter and car owner, entered his Kuzma dirt car for 22-years old Troy Ruttman. The car built by Eddie Kuzma was usual dirt camp car with shorter wheelbase and higher center of mass comparing to roadster. But better power to weight ratio and easier handling left some chances to Ruttman. The race was dominated by Bill Vukovich in Howard Keck’s Fuel Injection Kurtis roadster. Vukovich led 150 laps, but with 9 laps to go, he broke a steering linkage while leading. Ruttman inherited the lead and hold it until the checkered flag. Ruttman, aged 22 years and 80 days, set the record for the youngest 500 winner in history. It was also the last dirt track car to win at Indy.
