Here's the deal. No one knows what your combo is for sure, so it is hard to tell you what the timing should be. I would shoot for 28* total advance by 2500-3K rpm with the vacuum advance disabled. (Is the timing light a dial back type?) Then let the initial fall where it may.
It could be as much as 10* to as little as 2* initial with stock parts....all that is out the window if someone has diddled with your distributor innards in the past.
If you want to wake the car up, it needs a good bit of initial, but keep in mind that anything over 28* total on most slants is a recipe for pinging.
