But the exterior dimensions of the block are the same. The only difference is the blower that sits between the heads, and that can't effect crash standards. So something is fishy with all of this.

And this keeps the engine from joining the passenger compartment in a collision. But that is really reaching for a reason for his previous statement to be true, and this to be plausible.
Air space is air space.
