Holley provided us with a jet change set so that we could fine-tune our combination. We only had time to make one change, and we pulled the 65s that were in the carb and replaced them with 70s. We didn't really see any change in performance despite such a large numerical change in jet size. Pulling the air filter didn't do anything either, so we will look into a possible fuel supply issue as the reason for the lack of change.
