In a retro step, Cadillac entered a replica of the 1954 Series 62 coupe that a Colorado Springs dealer loaned to "five ordinary guys from Chicago", in order to revive a half-century old duel with Lincoln. The original rag-tag team won the last two stages, and finished third in class (a Lincoln Capri won the Large Stock Class). The newer car, built in-house by GM's Performance Division Garage, preproduction trim shop and show-car paint department, was built from an identical coupe hauled from somewhere within Cadillac's own inventory. The 331-cubic-inch V8 was enlarged to 398-cubic-inches, with higher 10.5:1 compression bringing output to and of torque, and certain safety improvements included. The car was reunited with Blu Plemons, the co-driver of the original (the driver, Keith Anderson, was killed in practice for the 1957 Indy 500) at the starting line. Among the nine other entries in the "Original Pan-Am" class were four Lincolns, including a 1949 model that contested the original Pan-Am.
