If you have to tilt your hood to fit an engine, you did what you had to do, but i would hope that you acknowledge there is a better way.


Here's an example from the domestic crowd

That's a poor "domestic" example since it's a Le Mans GT car. The radiator on those is also mounted in the rear, or is now, or was. Not sure what else is up front or if they're just controlling the air. Escaping air = using it. Of course just allowing it to run free would not serve any real aerodynamic purpose.

A cowl hood on a muscle car can serve the purpose of getting air into the carbeurator, that's what I always thought they were for anyway and mentioned above.
