What size engine is in the 1955 Ford f100?

The 1955 Ford F-100 uses a 239 cubic inch V8 engine, which was the standard and most common powerplant for that year.


In the 1955 model year, Ford’s F-Series trucks leaned on a larger, more capable V8 to deliver better performance for work and daily use. The 239 cubic inch V8, part of Ford’s Y-block family, provided a noticeable boost in power and drivability compared with earlier generations, helping to define the mid‑1950s pickup experience. That displacement translates to roughly 3.9 liters, with factory ratings around 140 horsepower depending on configuration and market.


Context and design


The 1955 F-100 sits within Ford’s mid‑1950s truck evolution, a period when the company standardized on a robust V8 option for its most popular pickup. The 239 cu in V8’s overhead‑valve design and larger displacement gave the F‑100 stronger acceleration, improved highway performance, and more capable towing potential for work and family duties alike. Today, that 239 cu in V8 is remembered as the engine that defined the era’s Ford pickups.


Summary


The 1955 Ford F-100’s engine size is best known as 239 cubic inches (about 3.9 liters), a V8 that defined the era’s power and helped establish the F-Series’ reputation for performance and durability.

A 1955 Ford F100's value varies significantly, with low-end prices starting around $19,495 for project trucks, average values around $49,993, and high-end prices reaching up to $129,900 or more for fully restored or high-spec models. Factors like condition, originality, and modifications heavily influence the final price.
 
Value breakdown

  • Low-end value: Approximately $19,495 for models in fair or project condition. 
  • Average value: Around $49,993 for a truck in good, average condition. 
  • High-end value: Up to $129,900 or higher for trucks that are extensively restored or customized, according to listings on sites like Classics on Autotrader. 
  • Specific auction examples: Some high-selling vehicles have reached prices like $126,500 at auction, notes Hagerty. 

Factors affecting value
  • Condition: A vehicle's overall condition is the most significant factor. A fully restored, rust-free, and well-maintained truck will command a much higher price than a project truck. 
  • Originality: Models that retain more of their original parts and are not heavily modified may be more desirable to some collectors, while others may prefer customized vehicles. 
  • Modifications: The type and quality of modifications play a big role. A professionally done "restomod" with modern performance parts like a Coyote engine can significantly increase value. 
  • Engine and drivetrain: The original engine and transmission, or desirable upgrades, will affect the price. For example, a classic Y-block V8 or a swapped modern engine will impact the value. 
  • Trim and options: Original options like a custom cab, power steering, power brakes, or power windows can add to the value, notes HowStuffWorks.
