Plug read, opinions needed
@Hysteric the motortrend carb test carries little weight because very little effort was made to even up the playing field through tuning. Look at JUST the wot afr on the tests. Even the author, Jeff Smith who is extremely knowledgeable, said many times through the article that further tuning needs to be done. I am of the opinion that shrinker is correct in saying how important vaporization is, but the tuning work has to be put in to each carb to make the results viable. Jet changes are not enough. I bet with proper tuning the larger carb on an NA 425 cube small block will be better everywhere. But not without effort.
