Good Initial Timing and Too much Total Timing Problem. Seeking guidance to minimize total timing. 1969 Swinger 340 4 Gear

Okay so just that I’m clear. I should keep carb vacuum hose disconnected and rev to 3000rpm. This should then be 32-36deg and after hooking up to distributor pot it should be 57deg at 3000rpm. What are those two terms called? I might have to search a video as I’m now confused.
57 is too much. That's why it's pinging. Set 35 with vac hose disconnected at 2600. Should make 50 when hose is hooked up
