I have an Edelbrock Performer 460 and a Holley Street Avenger 770 CFM on mine, and there are clearance issues with the hood. Other than the size of the engine, I attribute that to 3 things: a) 21" oval air cleaner, sandwiched between the hood and the distributor; b) 1/2" carb spacer to raise the carb enough to use the air cleaner; and c) the upward tilt of both the engine and the carburetor. All of this was installed by the previous owner(s).
I have some solutions in mind for my car, but starting from scratch a BB should fit as long as: a) the air cleaner is short enough to not interfere with the distributor and narrow enough to fit in the hood scoop (e.g. 8" x 15" or 8" x 12" oval); b) the intake manifold is relatively low profile; c) a minimal insulating spacer or turkey pan is used; and d) the carb and air cleaner follow the line of the hood scoop (I'm adding a 5° wedge spacer to tilt mine down 2°, rather than up 3° as it is now).
