What's needed to fit a 440 Six Pack under stock hood

When I was originally building the 440 for my Scamp I wanted to go with a six-pack but skipped it thinking it that it was not able to fit under the stock hood without a scoop, but recently saw this photo of a dart that has it with no scoop. Has anyone else done this? If so is that part of the hood support the only thing that needs to be clearanced? Here is the photo of that car.

A while back, there was a company making drop base, RB 6 pack air cleaners that looked factory like that. not sure if they're still making them or even if that is one but worth mentioning
