The Basics of Boring and Stroking
Before we dive into the specifics of a 350 bored 30 over, it’s essential to grasp the fundamental concept of engine boring and stroking. Engine boring refers to increasing the diameter of the engine cylinders to accommodate larger pistons. This process allows for increased displacement and improved performance.
On the other hand, stroking involves modifying the crankshaft’s stroke length to increase the engine’s displacement. By lengthening the piston’s travel distance, more air and fuel can enter the combustion chamber, resulting in enhanced power output.
Understanding a 350 Bored 30 Over
Now that we have a basic understanding of engine modifications let’s focus on what a 350 bored 30 over means exactly. The term “350” refers to the engine’s displacement, which indicates the total volume of air and fuel mixed in the cylinders during one complete engine cycle.
The number “30 over” signifies the amount of overboring done to the engine’s cylinders. In this case, the engine’s cylinders have been increased in diameter by 0.030 inches or 30 thousandths of an inch. This overboring process helps to achieve a larger piston size, thereby enhancing the engine’s displacement.
Benefits Of A 350 Bored 30 Over
By increasing the displacement of the engine, a 350 bored 30 over can offer several advantages:
- Increased horsepower: The larger displacement allows for more air and fuel to enter the combustion chamber, resulting in higher power output.
- Improved torque: The increased displacement also leads to enhanced torque, providing better low-end power and acceleration.
- Better throttle response: With additional air and fuel available, the engine can respond more quickly to throttle inputs.
- Enhanced overall performance: The combination of increased horsepower, torque, and responsiveness results in an overall improvement in the engine’s performance.
Considerations And Usage
It is essential to consider a few factors when deciding whether to opt for a 350 bored 30 over:
- Engine condition: Boring an engine requires careful inspection to ensure that it is suitable for the process. If the engine has significant wear or damage, it may not be advisable to bore it 30 over.
- Intended use: The decision to bore an engine should align with your desired usage. If you’re aiming for more power and performance, a 350 bored 30 over may be a suitable choice.
It is recommended to consult with an experienced mechanic or engine builder to determine if a 350 bored 30 over is the right modification for you.

Frequently Asked Questions For What Is A 350 Bored 30 Over Called
What Is A 350 Bored Over 30?
A 350 bored over 30 refers to a process of increasing the engine’s displacement by 0. 030 inches. It effectively increases the size of the engine, leading to potential performance enhancements in terms of horsepower and torque output. This modification is often done in the context of small block Chevy engines.
Is A 350 Bored 30 Over A 383?
No, a 350 bored 30 over is not the same as a 383. The term “bored 30 over” refers to increasing the cylinder bore size of a 350 engine by 0. 030 inches, resulting in a slight increase in displacement.
On the other hand, a 383 engine is a different engine altogether with a larger displacement.
What Makes A 350 A 355?
A 350 becomes a 355 when it undergoes a process known as “boring. ” By increasing the bore size by 0. 030 inches, the engine’s displacement is increased, resulting in a larger cubic inch capacity. This can lead to improved performance and increased horsepower.
What Is The Max You Can Bore A 350?
The maximum you can bore a 350 engine is 4. 030 inches, increasing its displacement. This can result in higher horsepower and performance. Make sure to consult with a professional for accurate measurements and to ensure compatibility with your specific engine.
Faq 1: What Does It Mean When An Engine Is “bored 30 Over”?
When an engine is “bored 30 over,” it means that the cylinder walls have been machined to increase the diameter by 0. 030 inches, resulting in a larger displacement and potentially increased power.
Conclusion
A 350 bored 30 over is a modification that increases the diameter of a 350 cubic inch engine’s cylinders by 0.030 inches. This process enhances the engine’s displacement, resulting in improved horsepower, torque, and overall performance. However, it is crucial to assess factors such as engine condition and intended use before considering this modification. Consulting with a professional is highly recommended to make an informed decision.
