Formula 1430

The Formula 1430 was founded in 1971 as the Formula Nacional. It was a junior formula racing series based in Spain.

History
Spanish car manufacturer SEAT launched the Formula Nacional in 1971. In the same era the Formula Ford (Great Britain), Formula Blue (France), Formula Vee (Germany) and Formula 850 (Italy) were launched. Many notable Spanish racing car constructors committed to the new founded series. Hispakart, Selex and Lynx are a few manufacturers to commit to the series. The first race of the series was run on April 4, 1971, at Circuito del Jarama. After a lengthy battle Selex driver Paco Josa won the championship over Lynx driver Emilio Zapico. The following years were dominated by the Selex ST 3. The ST 3 won all races between 1972 and 1976. The ST 7, launched in 1978, was less successful. Selex lost its dominance with the introduction of this new car. The ST 7 would win two championships 1980 and 1981. In 1980 the championship was won by Enrique Llobell. The following year the championship was won by Enriques brother Jose Luis Llobell. As of 1982 foreign built cars were allowed in the series. Selex completely pulled out of the championship due to disappointing results. With SEAT slowly pulling out of the series, the championship lost its notability and folded after the 1984 season.
