72 350 factory timing setting?

what was the correct factory timing setting for a 72 350 with 4bl and TH350 auto trans?

Also with addition of headers, small rv cam, and MSD electronic ignition set up what would most likley be a good all around timing setting for daily driving ad decent performance? I know every truck is different and will vary, but just a ball park at what setting people with similar set ups are running. Truck is ran at sea level for the most part...

I would start at 10 to 12 degrees btdc with the vacuum plugged at the dizzy, engine idle around 800 rpm. And then maybe 34 to 36 degrees @ 3600 rpm for advance.
