Boring and stroking....

I've had a few questions about this....stroking is basically making the stroke longer there for increasing liters, am i right? and boring is actually making the cylander wider, am i right?

So when you want to make a car a 2.0 liter for say, better torque...do you use a healthy mix of both stroking and boring, or do ya just bore the hell out of it til its a 2 liter?

Thanks for the info guys
