In 1952 Scuderia Ferrari entered Alberto Ascari as works driver to Indy 500 on a 375 model modified for specific oval track conditions. In addition three 375s were provided for American entrants – Johnnie Parsons, Johnny Mauro and Howard Keck. Only Ascari was able to qualify and take part in the race.
