Depends.

For an average driver - no. You can safely assume that the engine and all its parts are well sized for task it's asked to do. But for racers and tuners, who run their engines in another RPM range than average drivers, it can be beneficial to change to another pulley size. A smaller pulley will work just as well at a higher RPM, and free up a few HP that can be used to accelerate the car instead.

Since we don't know what car the engine's in, and many manufacturers made an engine this size, we can only go by this: If the car is ANYTHING but a Honda, there's generally a line on the crankshaft pulley and another on the engine block. If it's a Honda, the line is on the flywheel and there's a hole in the bellhousing to see it through.

How would a pulley be better than a ramp?

The pulley allows the re-direction of force by 180 degrees. A ramp cannot do that. Say you need to lift an engine out of a car's engine bay. You would use a pulley because as you pull straight down the engine goes straight up. That presumes that you weigh more than the engine.
