You would need the Weiand manifold to make more power and a set of mechanical carbs. It doesnt run great on the street unless you do the DC mods.
I’ll be modding up a two four barrel top for that bottom, two AVS carbs
Drifting off topic here a bit but Don Dulmage did that. It was good for 1.5 MPH on a 4150 lb car.
Based on his testing I'd have to conclude it would be the best multi carb manifold with the added bonus of it will still fit under a factory type hood scoop.
Not sure if the OP's idea of 6 pak induction would include an aftermarket intake or not.
