данные на моторы
OHC (LS, NE, N4), CVH (L6, R2), DOHC (N5, N8, N9) и V6 (PT, B4)
Взято из Интернета, откуда - не помню. Это данные для Сиерр и Скорпов, но моторы CVH там должны быть идентичны Фиестовским, а OHC и DOHC могут рассматриваться как идея для тюнинга.

На пассажирской стороне, где коробка стыкуется с мотором, на эдаком боковом выросте выбит полный трехбуквенный код. Если так хочется найти - найдешь.
Возможно, в каких-то случаях на Скорпы и N4 шли, но почему-то серьезные источники об этом не говорят, может быть из-за необычности таких ситуаций (ну, как хвостатый ТПС от OHC на DOHC, просто лежало их много на складах, вот и ставили).
А насчет разницы в буквах - там это с рециркуляцией отработанных газов и вскими подобными мелкими отичиями связано...
