Builders: Square engine, Over Square, or Under Square for you?

Obviously nothing about that engine is stock but it does show there's nothing wrong about the basic short block, bore stroke and rod ratio. Put a great top end on it and gonna get decent results even without adding stroke, and no reason to an extent that a 383 or even a 361 couldn't do well. And by well I mean the more average power people build for 400-600+hp not a 1000 + hp, 1.61 lbs-ft and 2.44 hp per cid.
But this thread is about "hypothetical" or the perfect engine, and preferences to the builder. We obviously can throw in real engines for comparison of all makes.
