I've always found 30 degrees is safe, 32 degrees if you're on a dyno or reading AFRs to watch it. There are "rules" about 1-2 degrees per 1lbs. per pound of boost and all that, but I've run numerous supercharged engines (intercooled and not) at 30 degrees total and they loved it. As said above, with load, you don't really want it all in too early. Should be at total around 3600 rpm. This is just old racer stuff.

I recall joe “Mild Thunder” had his Daytona Sensors mapped really well for his blown 468’s. I remember I was a bit surprised the advance at wot etc. Was a good thread or post.
Otherwise maybe dan “icdedpple” will chime in. With the newer advanced ignitions systems available today one can fine tune so much better than that of yesteryears!
And tailer to your own specific needs.

From there (safety) you can play with it, creep it up a bit at a time. You have the chiller, so that helps. Like Snapmorgan said, 35 is generally safe to 5#, 1 to 2 degrees out at 6-7#, should be right on the money without a computer to telling you what's happening.
