The 1985 model year
Overview
The carbureted 5.0 HO peaked at 210 hp — the most powerful carbureted Fox-body V8, thanks to a roller camshaft and freer-flowing exhaust — widely cited as the engine that closed out the malaise era. Mid-year, the SVO got a major upgrade to 205 hp (the '1985½' cars). A mild facelift sharpened the nose. (Horsepower figures are SAE net.)
