Why not build a 340?

I would step over free 360's to build a 340. I will take th bigger bore, shorter stroke and smaller main bearings all day long.

Even with a 4 inch stroke, there is PLENTY of overlap on the crank throws to not have to deal with those big main bearings.

Plus, when you are induction limited (and most guys are) I detest giving up rod/stroke ratio. But that is a discussion on engine geometry and beyond the scope of this thread.
