The SCCA Formula B class was created in the 1960s as a single-seat formula series with engine capacities not to exceed 1600 cc in capacity. The Formula Atlantic class began in England in 1971 and borrowed the rules form the US Formula B series. The engines, mostly provided by Costworth / Ford, were 1600 cc in capacity and featured twin-cams. The performance of the cars were similar to the Formula Two series but the cost was considerably less. This was the goal of the founder of the series, John Webb. The chassis of the cars were similar to Formula Two and Formula Three cars, which made production of the Formula Atlantic vehicles easier for the manufacturers that were familiar with the F2 and F3 series. Marques such as Chevron, Ralt, Lotus, Brabham, March, and Reynard produced vehicles for this series.
