Sunbeam Tiger, 1964-67. It was Carroll Shelby’s idea to fit a Ford V8 into the engine bay of the 4-cylinder Sunbeam Alpine. The initial series was fitted with a 260ci motor, the second series with a 289ci V8. The cars were built for the Rootes Group by Jensen Motors and Shelby received a royalty for each one produced, having missed out on building them himself. However production stopped once Chrysler took over Rootes as none of their V8s would fit and they did not want to rely on Ford to supply them.
