Understanding Engine Bore
In order to understand what a 350 bored 60 over means, we must first understand the concept of engine bore. Bore refers to the diameter of the cylinder in an engine. When an engine is “bored,” it means that the cylinder walls have been enlarged to increase the piston’s displacement.
The 350 Engine
The 350 engine, also known as the Chevrolet Small-Block, is one of the most popular engines used in various applications, including cars, trucks, and boats. It offers a great balance between power and reliability. The stock bore size for a 350 engine is typically 4 inches.
What Is Bored 60 Over?
When we say that a 350 engine is bored 60 over, it means that the cylinder walls have been enlarged by 0.060 inches. This enlargement allows larger pistons to be fitted into the engine, thereby increasing its displacement. As a result, the engine can generate more power and torque.
Benefits of Boring 60 Over
Boring a 350 engine 60 over offers several benefits, including:
- Increased Displacement: By enlarging the cylinder walls, the engine’s displacement is increased. This leads to more air and fuel being burned, resulting in more power and torque.
- Improved Performance: A 350 bored 60 over engine can provide a significant increase in horsepower and torque. This is especially beneficial for those looking for enhanced performance in their vehicles.
- Customization: Boring an engine allows for customization. It gives you the flexibility to choose different piston sizes and compression ratios, allowing you to tailor the engine’s performance to your specific needs and preferences.
Considerations
While a 350 bored 60 over engine can offer impressive performance gains, there are a few things to consider:
- Clearance: Boring the engine means that the cylinder walls are closer to each other. This can result in reduced clearance and potential issues with piston-to-wall clearance, especially if not done correctly.
- Compression Ratio: When modifying an engine, it’s important to consider the compression ratio. Increasing the displacement can impact the compression ratio, which may require adjustments to fuel octane requirements and engine tuning.
- Mechanic Expertise: Boring an engine is a precise operation that requires the expertise of a skilled mechanic. It’s essential to find a mechanic who has experience with engine modifications and understands the specific requirements of a 350 bored 60 over.

In Conclusion
A 350 bored 60 over refers to a 350 engine with enlarged cylinder walls by 0.060 inches. This modification increases the engine’s displacement, leading to improved performance and power. However, it is crucial to consider factors such as clearance, compression ratio, and the expertise of a mechanic when opting for this modification. When done correctly, a 350 bored 60 over can provide significant performance gains for your vehicle.
Frequently Asked Questions Of What Is A 350 Bored 60 Over
Can You Bore A 350 Chevy 60 Over?
Yes, it is possible to bore a 350 Chevy 60 over. By using domed pistons, you can increase compression and the octane requirement. It is recommended to consult with a knowledgeable mechanic for further guidance.
What Is A 350 Bored 60 Over With A 400 Crank?
A 350 bored 60 over with a 400 crank refers to a modification made to an engine. The original 350 engine has been increased in size using a technique called “boring” and the crankshaft from a 400 engine has been installed.
This modification enhances the performance of the engine by increasing its displacement, resulting in more power and torque output.
How Much Can A Chevy 350 Be Bored?
A Chevy 350 can be bored within certain limits, typically up to 0. 060 inches (1. 5mm) over stock size. However, it is important to consult with a knowledgeable mechanic who specializes in engine modifications for accurate guidance. Boring the engine beyond its recommended limit can cause detrimental effects on performance and durability.
Is A 350 Bored 30 Over A 383?
Yes, a 350 bored 30 over is essentially a 383. Boring out the 350 engine increases its displacement, resulting in a larger cubic inch capacity like that of a 383 engine. This modification can improve horsepower and torque output.
What Is A 350 Bored 60 Over?
A 350 bored 60 over refers to the process of increasing the cylinder bore size of a 350 engine by 0. 060 inches. This allows for larger pistons and increased displacement, resulting in improved performance.
