This is one of Bill Frick's famous "Fordillacs", basically a Ford with a Cadillac motor. Built at Frick's shop on Long Island, NY this one was said to be built with assistance from the famous sports car racer Briggs Cunningham in 1949. The car features Cadillac V8 power, a passenger compartment moved rearward, and front fenders stretched 18″. It is said to have been sold by Cunningham to Thomas Campbell of Campbell's Soup fame. Frick also built a series of "Studillacs" featuring the same Cadillac motors transplanted into Loewy-styled 1953-54 Studebakers.
** Doing a bit more research on his particular car, it appears that the Briggs Cunningham involvement was actually more through Alfred Momo, who was Cunningham's lead mechanic. Also, the car was apparently built jointly for Thomas Campbell and Argentinian race driver, Ralph Onunyzia. In any case, the Soup guy eventually ended up with it when he bought his "partner" out in 1952.
