Maximum advance curve on my 360
Billbo I still think the timing mark on your balancer is not accurate and your timing readings are probably 7 - 10 degrees off. I am running 32 total and all in @ 1500 with 14:1 and 105 octane fuel with no detonation. This is why I think your readings aren't accurate.
Granted if the car runs best at, as indicated on your balancer @ 27 degrees and is not detonating and you really don't care if it shows 5 or 100 degrees or whatever on the balancer then I would just run it as is. But if you start talking with some buddies or other Mopar guys don't say you only run 27 degrees total because I don't think you actually are running 27 degrees total, I'm thinking more like 37 or 38 total.
