Best Intake for a 408

Missing head and cam info. But, assuming it’s a mild Eddie type deal with a semi typical 240 ish@ 50 solid camshaft…I would run the airgap, and not think twice.
better all around manifold for something with the above parameters, and the dinky vert screams airgap too.
I ran the airgap on a 360 with lots more cam and vert, and a bit less compression, and the airgap was a great fit, car ran impressively for what it was.
I doubt a Victor would run better on the street or strip in such a combo
