Bore Engine Block
A bore is the diameter measurement of the cylinders in an engine. When the engine cylinder walls are damaged, the holes must be re-drilled to make them bigger for proper performance. This is referred to as a bored engine. Boring an engine is an economical alternative to buying a new one. By boring the engine block, the engine is reverted to its good running condition. You will now have fewer repair bills, better gas mileage, and overall better performance. To have your engine bored by engine experts, visit or call 909-629-7800 Engines R Us Pros today.
