overbored
Cylinder machined larger
Overbored describes an engine cylinder that has been bored out beyond its original diameter, typically to increase displacement or restore a worn cylinder wall.
The process involves machining the cylinder to accept larger pistons: The mechanic overbored the block to 0.030 over.
An overbored engine trades some cylinder wall thickness for added power or renewed life.
