The team's #11 entry is raced on road and street courses by series rookie Tatiana Calderon, who finished 24th on her series debut in last month's St. Petersburg season-opener.
But Hildebrand, who finished 15th in the Indy 500 with Foyt's team last year, will take over from Calderon for oval races at the Texas Motor Speedway, Indy 500, the Iowa double-header and Gateway.
