Intake manifold SB

Looking for input on which direction to go. I currently have a 318, may go with something else later but for now its what I have. It currently has a 2 barrel. I am looking to go to a 4 barrel and have seen many diffrent manifolds. Right now I am trying to choose between an aluminum edelbrock LD340 and a stock cast iron 1971 340 manifold. Im not looking to race but rather a good dependible street car with a little punch.

What are your recomendations and why?

Thanks
you didn't say whether or not you have dual exhaust and HEADERS, best bang for the buck IMO.
