Ported Victor W2

Well, admittedly I'm not either! But in this case, it's not just airflow, but mixture and charge distribution. I'm only going by the single plane manifold designs I've seen with the carburetor flange radiused to improve airflow. It usually follows the criteria if looking through the carburetor at WOT the runner divider will come close to intersecting the center of each diagonal sets of barrel, even if that means the dividers have to pushed back a little to establish that. Your plug readings may help determine some of what is happening. But yes, I would like to see his input here, too, as I believe he posted an article a while back on correcting the flow problems in a Super Victor.
