This 1977 Ferrari 512 BB is one of 929 carbureted examples produced between 1976 and 1981 and was first sold by Ferrari dealer Autorimessa Crivellari of Venice, Italy. Chassis 21513 was modified for its first owner by Carrozzeria AutoSport in Bastiglia, Italy, with riveted competition-style bodywork consisting of front and rear spoilers as well as wheel arch extensions. Finished in yellow over black leather upholstery, the car is powered by a replacement 4.9L quad-cam flat-12 paired with a five-speed manual transaxle. Other equipment includes overhead intake scoops, a roll cage, 15″ wheels with knock-off hubs, enamel Scuderia Ferrari fender shields, fog lights, air conditioning, power windows, Daytona-style seats, a leather-wrapped MOMO steering wheel, a gated shifter, Sabelt harnesses, and a Pioneer cassette player with a graphic equalizer. This modified 512 BB was acquired by the selling dealer in 2020 and is now offered in the Netherlands with factory books, tools, records, a set of 288 GTO-style mirrors, body-color intake covers, and Italian registration. The car is said to have been delivered from the factory in Rosso Chiaro and was repainted yellow after late-1970s modifications were completed by Carrozzeria AutoSport, which is now known as Bacchelli & Villa. The coachbuilder also worked with Ferrari on the development of the 512 BB LM client race cars. Custom aluminum aero equipment fitted to this example with exposed rivets included a 365 GT4 BB competition-style rear spoiler, a lower front spoiler, lower wheel arch flares, and roof-mounted intake scoops. NACA ducts have also been added to the lower front fenders. White #3 roundels and various logos were added in the 2010s. Additional equipment includes a rear high-mount spoiler, Vitaloni side-view mirrors, enamel Scuderia Ferrari fender shields, and fog lights. The pop-up headlights can be seen in the gallery along with a set of removed 288 GTO-style mirrors and body-color intake covers. The 15″ Ferrari-branded wheels wear three-eared knock-off hubs and are mounted with 225/50 front and 285/40 rear Pirelli Cinturato P7 tires that were installed in June 2020. A spare five-spoke wheel with a Michelin tire is fitted in the front trunk. The suspension system incorporates coil springs and anti-roll bars front and rear. The steering box was replaced in 2020. The cockpit features Daytona-style seats trimmed in black leather with red Sabelt harnesses, and black upholstery extends to the door panels, door sills, and center console and carpets. Equipment includes air conditioning, power windows, a gated shifter, a fire extinguisher, and a Pioneer cassette player with a graphic equalizer. The roll cage was added in the early 1980s and is adorned with ACI race verification stickers. The car has no recorded competition history according to the selling dealer. The interior photos were taken in October 2020. The leather-wrapped MOMO steering wheel frames Veglia Borletti instrumentation consisting of a 330-km/h speedometer, a tachometer with a 7k-rpm redline, and gauges for water temperature and oil pressure. Readouts for amperage, fuel level, and oil temperature are fitted in the center of the dash. The five-digit odometer shows 35k kilometers (~22k miles). The replacement 4.9-liter flat-12 was reportedly sourced from Charles Pozzi of Paris, France, and was installed under previous ownership. It features aluminum construction, dual overhead camshafts per bank, dry-sump lubrication, and quad triple-barrel Weber carburetors. An engine-out belt service was performed by Mugello Engineering of Hilversum, Netherlands, in August 2020. Other work at that time included repairs to one of the cylinder heads. Engine stamping F102B00 *00003* can be seen in the gallery. Power is sent to the rear wheels via a five-speed manual transaxle. Factory books and records are included in the sale. The car does not have a title, as it is registered in a country that does not issue titles for vehicles. It is being sold on its registration.
