Piggy back question to my timing a 360

Find zero with a piston stop and mark the damper . Not many are exact from the factory.

Did it! Got the dampener marked with time tape. Got the initial time set around 20*. When the advanced is hooked up and I rev to about 2500 it goes almost off the tape. Its reading about 60*. I'm sure my distributor is out of whack and needs to be adjusted. Only running a stock distributor.

Any thought?
