What exactly does increasing the stroke of your engine do?

I understand the basics of this. You put in a bigger cranks to the engine has a longer stroke, therefore a larger displacement. But what does it do to your hp/torque ratio as well as your redline. Since the piston is moving more I assume you would get a lot more torque but minimal horsepower. And since F1 engines have such a short stroke so they can rev to 18k, I would think a longer stroke would lower your redline.
