Engine families in the 1975 F-250


Below is a breakdown of the main engine families Ford used in the 1975 F-250, reflecting both base and heavy-duty powertrains.


Inline-six option


The staple six-cylinder powerplant was the 300 cu in inline-six, renowned for torque in work use and long-term reliability.



  • 300 cu in inline-six (4.9 L)


The 300 I6 served as the economical base powerplant across many F-Series configurations in that era.

  • 429 cu in V8 (7.0 L)

  • 460 cu in V8 (7.5 L)


Note: Availability varied by body style, trim level, and regional emissions regulations, so not every 1975 F-250 would have every engine option listed above.


Additional context


For a specific truck, consult the build sheet, window sticker, or VIN decoding to confirm the exact engine. The 1975 model year saw shifts in emissions equipment which could affect which engines were installed in certain markets.


Summary


In summary, the 1975 Ford F-250 offered a diverse engine lineup ranging from the 300 cu in inline-six to big-block V8s (360, 351M, 390, 400, 429, and 460 cu in).

Which F-250 to stay away from?


You should generally avoid the 2006, 2008, 2011, and 2017 Ford F-250 models due to common issues like the "death wobble," transmission problems, and other electrical and brake failures. Other models to approach with caution include the 2003-2007 F-250 with the 6.0L Power Stroke engine due to potential engine problems, and the 2008-2010 F-250 with the 6.4L engine, which has known EGR cooler issues. 
Model years to avoid

  • 2006: Known for stalling, power steering loss, and brake issues, along with the death wobble. 
  • 2008: Has serious brake problems and the death wobble. 
  • 2011: Often experiences transmission issues, rough shifting, and the death wobble. 
  • 2017: Plagued by the "death wobble" and other suspension/steering problems. 
  • 2017-2019: Specifically mentioned as being susceptible to the "death wobble". 
  • 2003-2007 (with 6.0L Power Stroke engine): Prone to head gasket and oil cooler failures in stock form. 
  • 2008-2010 (with 6.4L Power Stroke engine): Has common EGR cooler failures that can lead to coolant loss and overheating. 

General issues to be aware of
  • Death Wobble: This is a recurring problem in several model years, especially 2008, 2011, and 2017, and is related to suspension and steering components. 
  • Transmission Problems: Rough shifting and unexpected gear changes have been reported in certain years, notably 2011. 
  • Engine Issues: Specific diesel engines have known problems. The 6.0L and 6.4L engines are especially notorious for requiring significant maintenance or bulletproofing to be reliable. 
  • Brake Failures: Some models have reported brake problems, including sudden failure and issues with the brake booster.
