What does bored 30 over mean?

Each cylinder has been re-bored to a diameter .030" larger than it came from the factory. .030 oversize isn't much. It's done to correct slight cylinder tapering and to put the engine back into condition that it will last. It really isn't enough size difference to produce noticably more horsepower. Note that when the cylinder is bored .030 over, you'll also need pistons and rings that are manufactured to that size.
