I quickly took a few shots of mine that might give you a few ideas. I think this is what Houston was thinking about.
Notice I have curved both sides of the hood and put a peak in the middle. There is also a curve front to back that is barely noticeable. To give you an idea of the total length the stainless steel hinge that connects the two sides of the hood is 48 inches long. Both sides of the hood and hinge are removable to give good access to the engine bay by undoing one bolt at the front of the hinge.
