I am looking for a new snow blower and have discovered that the power rating
of the engines are no longer in "Horse Power" but in "Foot Pounds" if given
at all. Sometimes all that is given is the CC's of the engine.

Even the people selling these machines don't know what the "Horse Power"
ratings are so that old geezers like myself can understand what is going on.
Does anyone have any general rules regarding the conversion of Foot Pounds
or CC's to Horse Power?

Your best bet is to find old literature for small engines and make a
chart of displacement=hp. Then use that chart to determine approximate
HP of newer equipment where you know the displacement but not the HP.
It will be a fairly accurate guide.
