4 bbl intake 273

I know this question has been asked a million times but all
The threads I see are for 65 cuda's I have a 69 Dart 273 2 bbl. I want a 4 bbl, I thought I had my hands on a lb4d but it slipped away and I can't find anymore. What's a good 2nd place 4bbl intake manifold for my car? Also any recommendations on a 550 cfm carb? I'm looking at I dare say the edlebrock 1406.
