Information below from Wiki:
In Europe, the Pinto OHC was introduced in 1970 to replace the Essex V4 in the Mk3 Ford Cortina and Taunus V4 for the German Fords range (mainly the new Taunus TC). It was the first Ford engine to feature a belt-driven overhead camshaft (thus the name).
Applications:
Ford Taunus
Ford Escort Mk1 RS2000
Ford Escort Mk2 RS2000, Mexico
Ford Cortina
Ford Capri
Ford Sierra
Ford Granada
Ford Scorpio
Ford Transit van
TVR Tasmin 200
The Pinto engine was available in five displacements: 1.3 L (1,294 cc), earlier 1.6 L (1,593 cc), later 1.6 L (1,598 cc), 1.8 L (1,796 cc) and the 2.0 L (1,993 cc). Due to emission requirements it was phased out towards the end of the 1980s to be replaced by the CVH engine and DOHC engine, the latter being (contrary to popular belief) a completely new design and not a twin-cam development of the Pinto unit. The 16-valve version of the Ford DOHC unit is still used on the Ford Transit. The only DOHC direct derivative of Pinto engine is the Cosworth YB 16-valve engine, powering Ford Sierra and Ford Escort RS Cosworth variants.
