Is this a fresh engine or an engine thats been running fine and now has started to ping? Was it a used 340 with the cam and stuff added to it? Are you using an old points ignition or newer electronic?

I would find the highest octane fuel you can find and run it. No less then 91 and get 93 or higher if you can get it in your area.

38 degree's should be max on total advance. It may actually like it down around 34.

Total advance should be all the way in by 2500rpms or so.

You may have to change the vacuum curve a little bit or may find you dont need to even run a vacuum advance at all. Just plug the vacuum line off the carb.
