I have this on a blown flathead with a serpentine belt system. It's small diameter fits perfect behind the belt. I have a MSD electronic ignition and boost controller with a mallory performance coil, this distributor was a breeze to wire up, works great and looks good!

The pdf directions say to connect a ported vacuum line to the distro. Does this distro have provisions for vacuum advance at low RPMs? Or is it only mechanical?
