.EDIT
Moving here for discussion and my edumication
I've always thought I'd like to have an Edelbrock RB CH4B / MOPAR P/N 2836150 intake for a 440. Also looking at the Weiand Action+ and Eddy Performer (not RPM) and discussion in this thraed below (this was in the wanted to buy forum) I'm reconsidering and appreciate any first hand knowledge with any of these intakes.
CH4B
Weiand Action+ model 8009 (discontinued)
Edelbrock Performer
And stock 70 440 for reference / comparison
Here's one article I've read on these dual planes.
Intake Manifold Engine & RPM Range Test - Mopar Muscle Magazine
I'll see if I can locate another I remember that had several to compare.
