Proposed 400 bb build, cam recommendations

I think there is a slight problem with your selection of parts here. Your building a big block 400, correct? Then the only dual quad intake I know Edelbrock makes currently is for the 440. Unless you have an older cross ram or OEM intake?
I have the 5186, that's what I threw in the dishwasher in the what are you doing to your car today thread. I gotta bead blast it.
