CC's equate more to Cubic Inches. Foot pounds equate to horsepower.

cc and ci are both displacements, yes.

torque and horsepower aren't the same units at all---

Multiply horsepower by 33,000 to get foot pounds.

So a 3hp lawnmower has almost 100,000 ft-lb of torque??? Amazing! Them

Actually hp*33,000 -- ft-lbs/minute, _not_ ft-lb (as the table shows).
The "per minute" part is significant here.
