Actually, there is a real structural advantage to the flat engine over the
V. The block can be lighter in the opposed configuration, for the same
strength.

That's both true and, now that you point it out, relatively obvious. The
through-bolts take most of the loads so the case itself can be quite thin
and light. Something not possible with other configurations.

I wonder why I didn't think of it. Thanks for pointing it out.
