How much horsepower does a school bus engine have?

When specifying engines for your buses, you will notice that the engine rating has two numbers: horsepower (200, 220, 240, 260 etc.) and torque (520, 540, 600, 660 etc.). While these are related to one another, various applications have different needs in terms of the power or torque that are required.
