WDZ,
You are correct. For Dennis Olthoff's One Lap car, he enlarged the hood bulge and has a rear facing air intake at the rear end of the bulge. Here is a pic (there are ones that show it better, but couldn't find one quickly):
In my coupe (FTF), I have the requisite 351w block with the requisite Edelbrock RPM dual plane intake. I am using a CV Products drop-base air cleaner that will allow me to run a 3" high filter. It's about all you can do without doing something drastic to Mr. Brock's beautiful lines...
