Ford called the the EAO, or sometimes the OHC… but the rest of us- at least, those of us in North America- know this little workhorse as "The Pinto Engine."

What vehicles did the Pinto Engine motivate, other than the Pinto itself? A better question might be: which Ford vehicles didn't get the Pinto Engine? From its introduction in 1970 until the last Pinto-powered Ranger pickup in 2001, this engine was manufactured in displacements ranging from 1.3 to 2.5 liters and was installed in everything from the Cortina to the Aerostar. While many cursed its namesake car, even the most virulent Pinto haters were forced to admit that the engine was actually a pretty reliable powerplant. In turbocharged and intercooled 2.3 liter form, it cranked out 205 horsepower for the Mustang SVO, and those crazies at Cosworth got 224 horsepower out of a 2.0 when selling the RS500 for homologation purposes.
