The Super Victor is a single plane manifold with no real turns to make around any corners. Where would the fuel separate from the air flow as it negotiates a corner?
I haven't had a Super Victor in my hand to see how it differs from the normal Victor 340 but suspect that it may be too big. Add to that a large carb and you make it even worse. Case in point Qwkmopardan runs the normal Victor 340 on his 9 second 400+ cubes.
