How much horsepower does a 1978 Ford LTD have?
The horsepower of a 1978 Ford LTD depended on the engine under the hood. In general, base models with the 5.0-liter V8 produced about 145–150 horsepower, while larger V8s delivered more power, typically in the 180–210 horsepower range, depending on configuration and emissions controls.
Engine options and horsepower
The 1978 LTD offered several V8 engine choices, and horsepower varied by displacement and carburation. The following options cover the most common configurations found in 1978 LTD models.
- 5.0 L V8 (302 CID): approximately 145–150 hp (SAE net)
- 5.8 L V8 (351M): roughly 160–180 hp (SAE net)
- 6.6 L V8 (400 CID): about 180–210 hp (SAE net)
- 7.5 L V8 (460 CID): around 210–230 hp (SAE net) — available in some trims/markets
The exact figure for a given car could vary with carburetor type, exhaust configuration, and emission controls present in a specific model year or market.
Base engine: 5.0 L V8 (302 CID)
Large-displacement options: 6.6 L (400 CID) and 7.5 L (460 CID)
How horsepower was rated in 1978
In 1978, horsepower ratings used SAE net measurements, which reflect power available at the crank after subtracting the load of accessories and exhaust. With tightening emissions standards, the net figures were lower than earlier gross ratings, meaning a larger-displacement engine did not always translate to proportionally higher published horsepower. This is why numbers across models and years can appear inconsistent when comparing older catalogs to modern specifications.
Notes for collectors and restorers
When researching a specific 1978 LTD, verify the engine code on the data plate or original window sticker to confirm the exact displacement and horsepower rating. Variations in carburetion, exhaust, and emissions equipment between production runs can lead to small differences in power output.
Summary
The 1978 Ford LTD offered a spectrum of V8 engines, with horsepower ranging from about 145–150 hp for the base 5.0 L to roughly 210–230 hp for the largest 6.6–7.5 L options. The exact number depended on the engine, carburetion, exhaust, and emission controls, with SAE net horsepower ratings reflecting the standards of the era.
