Since I had the duel plane I just added a 1" spacer that was open, Actually it is an adapter plate from the spread bore to the 4150 flange.
My TB is still on back order so I installed a Holley until the TB comes in.

Interesting, thanks. I too seen on FItech's website that either intake is fine with their system but I'm concerned that the divided plenum of the dual plane would hamper fuel atomization of the spray so I have been researching whether a small open plenum single plane manifold would be better for spray distribution. Perhaps like a Victor Jr?
