I have a pair of the 600 CFM 1850 Holleys on a tunnel wedge set up. I'm on a quest to get them functioning as a pair of carbs designed for dual carb appication. Thruth , I can't remember ever getting into it long enough to notice if the secondaries ever opened.
I have the Mallory HyVI and have rev limmiter programed for 6,000 to keep everyting from going south. I still like those flow through aircleaner tops.
