I'm thinking of putting the Tower .75 engine in my second SSE. In my first one I had the OS 50 sx, and I liked it okay but now that engine is in my twist. The .75 seems like the same engine as the .61 except bored out which means same dimensions but lighter weight. What do you guys think? Will it even fit? From mounting flange to the other mounting flange the .75 is 8mm wider then most 46 size engines.

I'm building this from a kit, unlike the first one, and I've heard some guys say that it comes out fairly tail heavy so, if I need to add weight to the front I'd prefer to do it in the form of more engine weight.
