Welcome to the list!  I don't think we're too familiar with your particular
engine, but if it's not knock sensor equipped, you could probably advance
the timing to around 3 - 6 degrees BTDC (just a slightly educated guess). I
suppose a general rule of thumb for the 8v's would be add in enough advance
so it doesn't ping under load (going uphill in 4th for instance).  As for
actually setting this value, you can guess at it, by running advance
until it pings, but nothing replaces the timing light for making an
exact setting.  This may mean nothing if your distributor vacuum advance
isn't working properly...
