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

i wouldn't bother with those, they have 340 ports, go with what Rumble said. BTW the 71 340 intake is close to the ld340 in performance, too bad they didn't make them in aluminum.
