A B C E Which housing?

I'm fairly new to some of this modding stuff. On my 67 Barracuda, with the initial idea of narrowing a housing, I did a spring relocate, a mini tub and beat the snot out of the outer wheel house, hoping to gain some there also. I can trim or roll the lip if I need to.
It's not too late and I could always cut and square off the outer part of the wheel housing if that is going to be needed for the look I'm after.

After some research on the topic, I see a lot of people using un-cut B body housings, saying they fit better. Most of these people are running Darts.

Does this case hold true on the A-body Barracuda? Do I really need to narrow a housing?
I have 2, A-body housings and one B-body housing ( all of them complete).

I don't need a 'UGE tire as my horsepower will be around 400 with a small block. I am more after aesthetics.
I like the look of the tire being "tucked" in the wheel house. That look is easy on a Dart but the barracuda has a different wheel opening, as you all know.

My tire and wheel combination is up in the air at this point. I do want the LBP even though I do have a nice Kelsey Hays set up in the front. I'd like to say money is no object but I am willing to throw most of whats left of my money at the tire and wheel combo.
Did ya notice the lack of the word "budget" LOL.

I'm fairly old school but I do want a nice driving street car. The front will probably get the stock Mopar LBP swap with single piston calipers.

Well, that should get the ball rolling. I'm exited to hear your thoughts.
