I checked timing. Hopfully you can help me out if this sounds correct. Bumped engine till it pushed my finger off #1 spark plug hole. Moved balance to line up Mark's ( groove in blancer lined up to 0 on tab. Rotor is pointing just past #1 plug. Less than half way to #8
I don't have a piston stop to try it that way.

Sounds about right

The problem with giving it as much initial as it wants it your throttle plates end up closing too much which can mess with driveability. Which is why you might want to hook the VA to a ported source... that will artificially advance timing while idling but drop back once you crack the throttle .
