Foyt, but is primarily remembered for a fiery seven-car accident that resulted in the deaths of Eddie Sachs and Dave MacDonald. It is also the last race won by a front-engined "roadster", as all subsequent races have been won by rear-engined, formula-style cars. It was Foyt's second of four Indy 500 victories. Jim Clark, who finished second the previous year, won the pole position in the Lotus 34 quad-cam Ford V-8.
