What is the difference between an engine built for speed, and an engine built for power

Question

I’m thinking of a sports car vs. tow truck. An engine built for speed, and an engine built for power (torque). How do the engines react differently under extreme conditions? I.e being pushed to the max. What’s built different? Etc.

It’s really about the gearbox.

Same engine, let’s say petrol 4L V8, in a sports car it has a gearbox that allows for high rotation on the wheels, if you want a truck with the same engine it needs a gearbox that outputs lower speed but higher torque
