Guys, I spent an hour last night looking for specs on this COG debate even though it's OT AF.
There aren't any manufacturer released specs for cog that I can find for the Miata or Corvette, but rumor and pseudo science put it at about half an inch lower than the twins (C6z06 and ND) so I'm going to continue under that assumption.
However, if you dropped either of those engines in a twin Id bet the COG would move upwards, because the twins were designed around and optimized for the boxer layout. Likewise, if you could even fit an FA20 in one of the other cars, you'd wind up with a higher COG as well.
I think we can all agree that the layout of the engine and design cues off of it make up only a part of COG. Perfect example are the three cars we are talking about now. Both Miata and Vette are 2-seaters. As such, they had no worries about accommodating a rear passenger. This means no crash structure, and more flexibility in seating position of the front occupants. I've ridden in a C5, and you are definitely more laid flat than a twin. I imagine Miata is similar. Both of them have structures suitable for convertibles as well, meaning it's all down low. All these things are not true for the twins, necessitating higher overall structure.
Moral of the story, cog is entirely dependent on input requirements (performance, business, manufacturing, etc) that none of us will ever know beyond what marketing tells us, which may or may not be true. These happen to also dictate optimal engine configuration. Stop comparing apples to oranges ffs and stay on topic.
