Congrats on the new machine! Especially if it was free!!
I believe that's the model # of mine, a 1024 Pro, 24" bucket. Does that sound right for yours?
If so, one thing I've considered from looking at mine (relative to other engine options) is that the chute rotation controls attach to the cylinder head, bolting to the holes for the OHV valve cover.
You'd need to make sure that the engine would still permit mounting the chute bracket somehow.
It's already pretty powerful as is, with the 318cc OHV Tecumseh. Given the narrow bucket, I think you wouldn't make full use of a ~420cc engine unless you also used a larger pulley, to speed up the impeller & augers.
That way you throw further, and would also process & toss more snow per second, allowing a faster ground speed without the snow overflowing around the side of the bucket.
I've considered trying to make this change on mine. But with that much extra power on tap, I think it would almost be a waste NOT to speed up the impeller. Otherwise you'd somewhat rarely be able to fully load the engine. It was already a fairly high power-to-bucket-width ratio from the factory.
