It's the bean counters and warranty guys.
They don't want you putting too much timing in it causing warranty issues.
And it also likely says somewhere in the paperwork not to run more than 10 degrees initial.

I am with you....1 geezer to another  Yes you can run that mill with no vac advance....but it will KILL the fuel mileage ! On the street, I would suggest 32-34 total, in tween 2800-3200 (depending on gears/ect). Shoot for about 10 degrees @ the crankshaft, on the vac advance, & hook to full manifold source. If you are a street cruiser, I will bet that you will like the curve? On the track, we set @ 38, all in @ 2600...no vac advance. On the street, your plugs will burn cleaner, & your engine will run cooler, with that vac can longhorn
