Testing commenced immediately after at Modena Autodromo with Ronny Peterson. Chassis 1004 then traveled down to Vallelunga, and finally, in search of sun and warmth, made its way to Autodromo Pergusa in Enna Sicilia, where Vaccarella P tested it with different set-ups as well as different nose and tail configurations. The information gathered was used on 1004 and its sister cars to run the 24 hrs of Daytona in January 1970. While testing in Florida, Mario Andretti found that, in Enna trim, the 512S would be an absolute force at the 24-hour race. Enna trim was Series 1 nose and Daytona tail.

Daytona 24HR: SEFAC entered Chassis 1004 into the Daytona 24HR race as Ferrari #27, in Enna trim with external door hinges, allowing for a more rapid driver change in endurance racing. Jacky Ickx and Peter Schetty were the drivers; 1004 qualified 5th but DNF, as Ickx suffered a puncture in the 6th hour that severely damaged the rear suspension, forcing the car to retire.

Monza 1000KM: SEFAC (Società Esercizio Fabbriche Automobili e Corse) entered Chassis 1004 as Ferrari #2 and was driven by John Surtees/ Peter Schetty. 1004 qualified 6th with a time of 1:26.7. The coupe now wore a re-profiled, higher downforce Series ll nose and slats over the water radiator air exits, a mirror on the roof (visible through a small window in the roof panel), and external door hinges, retaining the two fender wing mirrors. 1004 finished 3rd Overall.

5/3/1970

Targa Florio: SEFAC entered Chassis 1004 as Ferrari #T6 as a practice car for Vaccarella/ Giunti. It was presented as a spyder with severely cut-down side windows, internal door hinges, a spyder tail, and advertising decals. It was different from the prepared race car Chassis 1012. Vaccarella damaged 1004 in practice, and it was sent back to Maranello for repairs.
