Carb and intake suggestions

If you are keeping things the way they are, my recommendation is definitely the air gap, especially if the converter is 3xxx any flash, which seems hard to believe if it’s an 8 inch
Carb wise, 950 Holley.
If the converter had more flash and you had more gear, the Victor would work well, but you don’t, so it would be mighty soggy on the street with your vert and gears with that single plane.
I had that Mopar single plane on a stock stroke 360, didn’t like it, replaced it with an air gap, car ran 11.20’s ultimately with the airgap. Not an intake to underestimate, it works on most everything
