Default What do they mean by "Blue printed and balanced" ?

I have read it in many magazines and they refer to an engine getting blue printed and balanced. I was wondering what it means and what it involves.

Thanks

Default Wiki

Usually to take the original design of the engine with the dimensions and tolerance information then spec out to a tighter tolerance, each component against the blueprint or drawing. Ideally, blueprinting is performed on components removed from the production line before normal balancing and finishing.

This takes a lot of time and effort and money.

You want to do this to the critical components to assure performance is at maximum.

Component Balancing
In order to achieve the inherent balance of any engine configuration, the balancing masses must be matched. In most engines, some individual components are matched as a set. Exactly which components are matched is part of the design of the engine.

For example, pistons are often matched, and must be replaced as a set to preserve the engine balance. Less commonly, a piston may be matched to its connecting rod, the two being machined as an assembly to tighter tolerances than either alone.

Component balancing is not restricted to considerations of mechanical balance. It is vital, for example, that the compression ratio and valve timing of each cylinder should be closely matched, for optimum balance and performance.
