You can definitely run under the index w/ a single carb. I used to run SS/PCA in IHRA, which is a single dominator that would fit in SS/BM at NHRA events and could run a couple tenths under but that's it. There's usually around 30 more hp w/ two carbs but I didn't have $2000 for another intake plus the cost of a set of carbs.
