Default Holley secondary vacuum canisters on dual quads
Still planning to spring for a set of correct, restoration, custom tuned carbs for my motor. Mickmate has suggested someone that he has had a lot of good experience with. The original carbs had a vacuum hose joining the secondary canisters together to equalize opening of the secondaries. Most Holleys don't have anything like this as I assume it's only usefulness is in dual quad and tri-power set ups. Is the vacuum port secondary cap a Holley option? Or is it a rare, original, scace as hen's teeth part with a hefty price tag?
