What Is a 350 Bored 30 Over? Uncover the Hidden Power.

Published by Dustin Babich on

A 350 bored 30 over is an engine block that has been machined to a larger size, resulting in increased displacement. This means that the cylinder walls have been bored out 0.030 inches larger than the original size, allowing for larger pistons to be installed and more air/fuel mixture to be compressed and ignited within the engine.

A 350 bored 30 over is a popular upgrade for those who are seeking more power and performance from their engine. This modification can help increase horsepower and torque, allowing for quicker acceleration and improved overall performance. It’s important to note that this modification requires careful attention to detail and should only be performed by a skilled professional.

With the right expertise and attention to detail, a 350 bored 30 over can help take your engine’s performance to the next level.

The Basics Of Boring An Engine

Boring an engine is the process of creating more space in the cylinder. The engine can be bored out to accommodate bigger pistons. Honing comes in after boring to create a better, smoother finish on the cylinder walls. One of the pluses of boring an engine is developing higher horsepower.

These extra horses are obtained from the increased displacement that comes with the enlarged cylinder. However, the disadvantage of boring an engine is the potential risk of weakening the engine block. No matter what, an experienced mechanic should handle any sort of engine boring.
