Best dual plane intake for 400 low deck

Have to verify the gears( my guess 2.76 or 2.94 unless I luck out with a 3.21) and no to a cam anytime soon.225/75r15 currently.
I have several variations of 750cfm on hand to choose from. Anything else would have to be acquired .

I have either Hooker super comp 1 3/4 long tubes or Schumacher tri-y headers that I will ad when changing to dual exhaust.
I would 100% use the Schumacher tri-y's in a heavy C-body with no gear. A 383 rr with 3.23/3.55 would get long tubes.
