best air cleaner to use?

I am running an edelbrock carb on my 1973 340 duster on a wiend manifold. whats a good air cleaner to go with . the guy I got the car from put a small 6 inch diameter deal on the car with fairly narrow element. I like the look of the mopar perf. 10 inch model as I was told by a few guys that the small one I have on now is not giving the needed air to the engine, so should I go to a wider unit and as wide filter that will fit under my hood? thanks for any info
