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?
This one if for a 62 383/343 hp
I have a marine one for 413/426
