Ford Pinto engine
It was used in many European Ford cars and was exported to the United States to be used in the Ford Pinto, a successful subcompact car of the 1970s, hence the name which is used most often for the unit. In Britain, it is commonly used in many kit cars and hot rods, especially in the 2 litre size.
De Tomaso Pantera
Late in 1971, Ford began importing Panteras for the American market to be sold through its Lincoln Mercury dealers. The first 75 cars were simply European imports and are known for their "push-button" door handles and hand-built Carrozzeria Vignale bodies. A total of 1,007 Panteras reached the United States that first year. As with most Italian cars of the day, rust-proofing was minimal and the quality of fit and finish on these early models was poor with large amounts of body solder being used to cover body panel flaws. 
Several modifications were made for the 1972 model year Panteras. A new 4 Bolt Main Cleveland Engine, also 351 cu in, was used with lower compression ratio (from 11:1 to 8.6:1, chiefly to meet US emissions standards and run on lower octane standard fuel) but with the more aggressive "Cobra Jet" camshaft (featuring the same lift and duration as the 428 Cobra Jet's factory performance cam) in an effort to reclaim some of the power lost through the reduction in compression along with a dual point distributor. Many other engine changes were made, including the use of a factory exhaust header.
