Editing Formula Two (section)

=== Formula Junior (1961–1963) and 1-litre Formula Two (1964–1966) ===
[[Formula Junior]] was introduced in 1959, an attempt to be all things to all people (both a training formula replacing Formula Three and a high-level international category below Formula One replacing Formula Two), and it was soon realised that there was a need to split it into two new formulae; Formula Two and Formula Three were reintroduced for the 1964 season, with Formula Three requiring one-litre production-based engines, which were similar to Formula Junior with very restricted tuning, and Formula Two also having a 1.0 L engine size, but permitting pure-bred racing engines. Formula Two was largely the domain of Formula One stars on their days off. Engines were mostly by [[Cosworth]] (based on Ford blocks) and [[Honda]], though some other units appeared, including various [[Fiat]] based units and dedicated racing engines from [[British Motor Corporation|BMC]] and [[British Racing Motors|BRM]].
