5 or a 5.5 horsepower engine
A two stage snow blower will blow snow further. I would get let a 8 hp or longer to make sure it can handle the wetter snows.

To convert cubic centimeters (cc) to horsepower (hp), a rough estimate is that 1 hp is approximately equal to 15-20 cc for small engines. Therefore, a 205 cc snow blower would typically have around 10-14 hp. However, actual horsepower can vary based on the engine design and efficiency, so it's best to check the manufacturer's specifications for precise information.
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.
Most lawn and garden equipment motors run about 1 HP for every 25CC ... so a 357 would be somewhere around 12-14 HP.
