Re: spark advance table
^ what he said or start with a AUJL L98 bin. Much less timing for iron head fbody motors. Then take that table, zero out PE spark but add that back into the main table, and smooth it all out. Make max timing around 34 deg for now and bring it all in by 2800 rpm or so and your good to go.
