We are trying to sell our 1991 F250. A question that has come up is which engine does it have? A windsor or modular. Does anyone know what to tell?

Thank You
Jennifer

Either the 300 Inline 6 cylinder, 5.0L (302) v8, 5.8L (351) v8, or the 7.5L (460) v8, or the 7.3L (444) Diesel. Either the engine intake will have this on it or the Emissions label somewhere under the hood.

If it is the 5.0L or 5.8L, it is a Windsor. Modulars started in 97-later F-150s and 99-later Super Duties.
