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.)

Year over year

What changed

  • The carbureted 5.0 HO rose to 210 hp via a roller camshaft, revised lifters, and a tubular exhaust — the peak carbureted Fox V8.
  • The CFI (automatic) 5.0 rose to ~180 hp.
  • Mid-year, the SVO was upgraded to 205 hp (the '1985½' cars: smaller turbo housing, larger injectors, more boost) and got revised aero/flush headlamps.
  • A facelift revised the front fascia and grille.

Worth knowing

Notable

  • Peak carbureted 5.0 HO (210 hp) — a high point for the carbureted Fox V8.
  • The 205-hp 1985½ SVO is the most desirable SVO.

Living with it

Reliability & ownership notes

  • The 210-hp 4-bbl 5.0 is a strong, durable engine; keep the Holley properly tuned.
  • 1985½ SVOs are the most powerful and most sought-after SVOs but the hardest to find parts for.
  • Inspect for Fox-body rust.
