383 intake / carb help for my 73 Dart

PopDart, if you want to upgrade the carburetor, this would be a good one.

650 vacuum secondary Holley. Spread bore so it will bolt right on. And it's cheap.

I still recommend maximizing what you have before changing. At least though, with that 650 you will have something to upgrade to when you want to.
