I just bought a MSD Ready to Run Distributor with Vaccum advance. MSD installed the heavy (slow) advance springs and the blue 21 degree advance bushing. They included two additional sets of springs blue and silver. They also included three other advance stop bushings Red 28 degrees, Silver 25 degrees and Black 18 degrees. My question is what would be a good base line to start with? I have a mild 350 4 speed car. I don't know what cam is in it, but I think the previous owner went with the Edlebrock Performer Package. I have performer intake and 600 edlebrock carb. Other than those upgrades, I think the rest of the engine is stock. Thanks in advance.
