Stock stroke 440 with iron heads probably doesn't need a Super Victor so I think the M1 4500 would be the best choice. The M1 4500 had standard size runners but a nice large plenum and a 4500 bolt pattern. It also isn't super tall so it should fit under the hood you are currently using. You would probably have enough room for a 1 inch tapered spacer. The intake plus a spacer should still be less money than buying a new 4150 carb. This picture shows low deck M1 4500 intakes but they'll give an idea of what to look for. Just watch out for the wider Stage VI versions that are floating around. You don't want one of those.
