Seeking advice intake manifold

I have stock engine and parts, 73 Duster w/ 340. Considering upgrade from the stock manifold, but which one?
I am street driver, with AC, p.s., p.b., auto tran. Do not want to cut up hood. Do not want to change air breather.
Am willing to buy new carb too, if that's a real help.
Suggestions? Or am I limiting myself so much that there's no use in seeking a change?

I'm going to Carlisle soon, will expect to find many used parts available...
