Displacement doesn't directly equivocate to horsepower.
8.0 horse power - 125 cc
the cubic centimeters of 6.5 horse power is 175 cc
I've researched the same thing, last year actually when buying a 305 cc snow blower with a Briggs engine... I've heard it's comparable to 10 horse but there's no scientific way to convert CC's to horsepower. I can tell you that living in a snow belt in Ontario, the 305 CC's holds up just fine.
10 horse power
It's about 5.5hp
50 horse power
200
Depends on how much money you have to spend
