Setting it at 0 usually works, but most instructions advise setting it at 12. That gets the static timing as close to where it needs to be initially. Initial timing on a Chevy is never going to be 0, so why set it there?
you set it there as a starting point, so youll know where to set the rotor. before i put my dist. in im going to set the timing mark on the HB at 0 (or somewhere close) on my timing tab, drop the dist. in on #1 wire in the cap, put a timing light on it and set the timing, to what ever i wont it. untill you put the dist in and hook up a light i cant see how you would know where to set the dist to give you 12 degrees. you can find 12 degrees on the HB with a tape, but where is 12 degrees in the dist?
