because have you ever actually looked under the hood of a F-body? Unless it has a FAST intake manifold, you cant see any other mods. You cant see if it really has long tubes, (obviously a cam) heads with a casting number etc…
basically, everyone knows what under the hood of a stock f-body looks like…no need to show it.
I think it was more of along the lines to show under the hood of the new 5.0. I dont think it had any other reason.
