Packages available for the 1970 model year: Standard, Convertible, XR7, GT, Eliminator
The 1970 Cougar appearance wise was similar to the 1969 model, however there were numerous changes inside and out. It now sported a new front end which featured a pronounced center hood extension and electric shaver grille similar to the 1967 and 1968 Cougars. Federally mandated locking steering columns took place on the inside, and the aforementioned new nose and taillight bezels updated the look on the outside. The 300 hp (220 kW) 351 “Cleveland” V8 was now available for the first time though both the Cleveland and Windsor engines were available if you took the base model 2-barrel motor. The 390 Ford FE engine was now dropped from the lineup, and the Boss 302 and 428CJ engines soldiered along.
