Single plane manifold on the street
Call Bob Mazzolini and ask him. This guy has record setting engines in a whole bunch of Mopars and he is a great guy to deal with. He is located in Riverside California.http://www.bobmazzoliniracing.com/
If you want wicked fast, he is one of THE guys to deal with. If he gives you advice, it's not because he will make more money on a particular part....he knows what works.

If there is a perfect intake for your combo, he will know what it is. You should see the wall of badass cars behind his desk in his office. Very impressive and a great guy.
