If you're setting the timing just to get it to start, you need to find TDC manually (the pulley may not be lined up properly after the rebuild), position the rotor at TDC, and stab the distributor so the ignition rotor in the distributor is pointing at the contact for the front #1 leading spark plug. This will give you roughly 0° advance at idle and should be enough to get it started. You can set the ignition timing anywhere you wish after that.
