What is the bore size of a 302 Ford?
The bore size of a 302 Ford engine is 4.00 inches (101.6 mm). This is a key specification that determines the engine's displacement and performance characteristics.
What is the 302 Ford Engine?
The 302 Ford engine, also known as the 5.0L V8, is a popular small-block V8 engine produced by Ford Motor Company. It was introduced in 1968 and used in a wide range of Ford, Lincoln, and Mercury vehicles throughout the 1970s, 1980s, and 1990s. The 302 engine is known for its reliability, power, and relatively compact size compared to larger V8 engines.
Bore Size Explained
The bore size of an engine refers to the diameter of the engine's cylinders. In the case of the 302 Ford, the bore size is 4.00 inches (101.6 mm). This, combined with the engine's stroke of 3.00 inches (76.2 mm), gives the 302 a total displacement of 302 cubic inches (4.9 liters).
The bore size is an important factor in an engine's power and efficiency. A larger bore size generally allows for more airflow and fuel delivery, resulting in increased horsepower and torque. However, larger bore sizes also increase the engine's overall size and weight, which can impact factors like fuel economy and vehicle handling.
Importance of Bore Size
The bore size of an engine is a critical specification that affects several key performance characteristics:
- Displacement: The bore size, combined with the engine's stroke, determines the total displacement of the engine, which is a measure of its size and power potential.
- Airflow and Fuel Delivery: A larger bore size allows for increased airflow and fuel delivery, which can result in higher horsepower and torque output.
- Engine Efficiency: The bore size, along with other factors, affects the engine's efficiency and fuel economy.
- Engine Cooling: The bore size can impact the engine's cooling requirements and the design of the cooling system.
Understanding the bore size of an engine, such as the 302 Ford, is essential for anyone interested in engine performance, modifications, or replacement.

What is the bore size of an olds 307?
307. A slightly larger 5.0 L (5,033 cc; 307.1 cu in) version was introduced in 1980. It uses a 3.8 in (97 mm) bore (in common with the Buick 231 V6 and 350 V8) with a 3.385 in (86.0 mm) stroke.
What's a 302 bored 30 over?
It means that each cylinder was bored . 030 or 30 thousandths of an inch more than the stock measurement. It actually makes it larger than a 302. It will affect things if you ever have to rebuild again.
What is the stock bore size of a Ford 302?
4-inch
With a 4-inch bore and a 3-inch stroke, the 302 had the potential to make great power, but it was all at high rpm. When Ford found the need for a more powerful small-block with lots of low-end torque, it went with the 351 Windsor, a derivative of the 302, albeit with a raised deck to accommodate a longer stroke.
What is the horsepower difference between a 302 and a 351W?
Run in this manner, the Boss 302 produced peak numbers of 374 hp at 6,700 rpm and 324 lb/ft of torque at 4,300 rpm. Stepping up to the larger Boss 351 resulted in peak numbers of 383 hp at a slightly lower 6,200 rpm and 391 lb/ft of torque at 4,000 rpm.
What is the bore size of a Ford 351W?
FR Boss 351W
Maximum displacements are 4.25 in (108 mm) stroke and 4.125 in (105 mm) bore.

What is the stock bore of a LA 318?
The 317.5 cu in (5.2 L) LA 318 has a bore and stroke of 3.906 in × 3.312 in (99.2 mm × 84.1 mm), identical to the A 318 it was derived from.
What is the stock bore size of a 7.3 Powerstroke?
The Power Stroke is an electronically controlled, direct injection engine with a 4.11 in × 4.18 in (104.4 mm × 106.2 mm) bore and stroke creating a displacement of 444 cu in (7.3 L).
What is the bore size of the Cleveland 302?
4.000 inches
Cleveland castings received a circled “CF.” Some blocks were devoid of any kind of foundry identification, which makes it tricky to identify them. To achieve the 351's displacement, Ford had to raise the 302's deck 1.28 inches to accommodate the 3.500-inch stroke. Bore size remained the same at 4.000 inches.
