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 are some stout crankshafts...

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

Yes, "per minute" is the key. Same as how horsepower is measured.

"Horsepower is defined as work done over time. The exact definition of
one horsepower is 33,000 lb.ft./minute. ...

Well, DOH! if 1-hp * 33,000 ft-lb/min/hp = 1 hp I guess it would follow
that the definition of 1 hp == 33,000 ft-lb/min...
