distributor
Working on my just bought 65 BB and find I have no vacuum advance on the distributor, it does have the tachometer drive and everything works great, the engine runs great and is a real screamer. I haven’t removed the cap yet, but am assuming it’s an electronic ignition.
Would it have an electronic advance?

My guess would be that you'll find centrifugul (mechanical) advance underneath the rotor. I think that a lot of the performance oriented aftermarket distributors don't provide vacuum advance, although you can get them from MSD, among others. If you have an external ignition controller, it is possible that it is dialing in advance electronically, but I would guess that the centrifugal is all that your engine is getting--and from your description of its performance, might be all that it needs!

You will find that a vacuum advance provides both better fuel economy (at both idle and cruise), and cooler running (especially at idle).
If those are not concerns, then the cent. advance only dist. works quite nicely.
Your dist. "could" have an electronic module tucked inside, which replaces the original points (I know of 3 versions available). But they do not have any additional advance (they just replace the points, and for optimum performance, the matching coil should also be used).
