What is the bore size of the Ford Model A?
The Ford Model A, produced from 1927 to 1931, had a bore size of 3.875 inches (98.425 mm). This was the diameter of the engine's cylinders, a key specification that determined the engine's power and performance.
Understanding the Bore Size of the Ford Model A
The bore size, also known as the cylinder bore, refers to the diameter of the engine's cylinders. This measurement, along with the stroke (the distance the piston travels up and down), determines the engine's displacement or total volume. The bore size is a critical factor in an engine's design, as it affects the engine's power output, efficiency, and overall performance.
The Ford Model A was powered by a four-cylinder engine with a bore size of 3.875 inches (98.425 mm) and a stroke of 4.25 inches (107.95 mm). This resulted in a total displacement of 201 cubic inches (3.3 liters), which was a common size for automobiles of that era.
Importance of Bore Size in Engine Design
The bore size of an engine is important for several reasons:
- Power Output: A larger bore size allows for a larger volume of air-fuel mixture to be drawn into the cylinder, resulting in greater power output.
- Efficiency: The bore size, along with the stroke, affects the engine's compression ratio, which is a key factor in determining the engine's efficiency and fuel economy.
- Durability: A larger bore size can also contribute to the engine's durability, as it allows for a larger surface area for the piston to move against the cylinder walls, reducing wear and tear.
In the case of the Ford Model A, the 3.875-inch bore size was a well-suited design for the era, providing a balance of power, efficiency, and reliability for the vehicle.
Conclusion
The Ford Model A, a classic American automobile, had a bore size of 3.875 inches (98.425 mm), a key specification that contributed to the engine's performance and overall design. Understanding the importance of bore size in engine design helps to appreciate the engineering behind this iconic vehicle.

What is the bore size of a Ford Model T?
The engine's bore was 3+3⁄4 inches (95.25 mm) and its stroke was 4 inches (101.6 mm) even, for a total displacement of 177 cu in (2.9 L).
Can you bore a 351 to a 427?
In short, starting with a Dart 351W block, boring/stroking to 427 cid and utilizing a host of performance aftermarket components, we were able to build a streetable large-displacement “small-block” Ford engine capable of producing around 600 hp.
How many miles per gallon did the 1931 Model A get?
The engine was an L-head 4-cylinder with a displacement of 201 cubic inches . This engine gave the car 40 horsepower. Typical fuel consumption was between 25 and 30 mpg using a Zenith one-barrel up-draft carburetor, with a top speed of around 65 mph.
