In light of theCan Am Series' folding the previous year, the Formula 5000 Championship became the SCCA's flagship series in 1975. However, only two years later, theFormula 5000 category would form the basis for a revived Can Am Series. After 1975,Lola's dominance would end asMarch andShadow cars would win events the following year. It would also be the end ofChevrolet's several year sweep of the championship as an engine manufacturer, as aDodge powered car would garner a victory in 1976.
