Mallory's electronic Y-Block distributor does not have a vacuum advance. So, if you are building a blown Y-Block where you would normally block off the vacuum advance anyway, would this be a better choice than a '57 and later Y-Block distributer with a Pertronix ignition? I was going to use a Barry Grant Carb with mechanical secondaries set-up with a blow through.

Thanks,
