The Fiat 124 Sport Coupé is a two-door, four-seater notchback coupé produced by the Italian automaker Fiat in three generations between 1967 and 1975. It was based on the Fiat 124 saloon. Its four cylinder aluminum and iron, twin overhead cam 'Lampredi engine' was designed by ex-Ferrari engineer Aurelio Lampredi. Originally, the AC, or first generation, featured a 1,438 cc engine, which grew to 1,608 cc in the second, or BC, generation. The third generation, or CC, was first officially offered with the 1,592 cc and later the 1,756 cc engine (some early CC models left the factory with left over 1,608 cc engines). Equipment included a 5-speed gearbox (although very early AC models featured a 4-speed), four wheel power disc brakes, double wishbone front suspension, one carburetor per cylinder (Two dual-choke Weber or Solex carburetors on the BC series 1608 engine - except for the USA version which received mild carburation due to emissions constraints), electric fuel pump (on the CC series), and suspension by coil springs. The Fiat 124 Sport Coupé was also built under license in Spain with 1600 (FC-00) and 1800 (FC-02) engines as the SEAT 124 Sport. Design The 124 Sport Coupé was designed as a three-box, 2-door notchback coupé by Mario Boano, known for styling the bodywork on the Ferrari 250 GT "Boano". As many parts as possible were used from the 1966 FIAT 124 Berlina saloon. Boano was hired by FIAT and made responsible for the in-house Centro Stile Fiat, while the iconic softtop Fiat 124 Sport Spider, which also shared the same basic platform as the 124 Sedan but rode on a 14 cm shorter wheelbase, was outsourced to famed Italian carrozzeria Pininfarina. Approximately 113,000 AC Coupés, 98,000 BC Coupés 1438 cc/1608 cc, and roughly 75,000 CC Coupés were manufactured. There were ongoing changes with all models making them almost individual by year (e.g. lack of rear sway bar on 1969 ACs, etc.) The Fiat 124 Spider Abarth came with dual Weber 44 IDF carburetors unlike the regular 124 coupés and spiders which were equipped with dual Weber 40 IDF carbs. Fiat twincam engines tend to be oversquare, with a larger diameter bore than length of stroke. The 1608 cc, however, is a perfectly square engine, 80 mm by 80 mm, allowing it, when combined with dual camshafts and proper carburetors, to rev to high rpms. Engines 1400 (1438 cc) - 1600
