Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I have a 2010 Platinum 24.  I only seem to use it for EOD duty and the occasional heavy storm.  I use my singe-stage for everything else.  Could I optimize my Ariens by removing the stock 250cc Polar Force engine and bolting on a bigger engine...let's say a 342cc or something similar?  Is there a bigger Briggs (Polar force, Intek, etc.) that would mount on that frame and accomplish my objective without too much modification?  The stock engine is ok, but if my goal is to cut down the EOD pile and be able to throw it across the street would the big motor/24" bucket combo get me there?  I don't care about the warranty.  Can anyone recommend a specific engine for this project and the associated parts (pulleys, belts,etc.) that might be required?  And of course some extra shear pins!
