What should I be targeting for a distributor curve for my stockish 67 Coronet 383?

Initial? Total? All in at what rpm?

It is a street car that we take down the track occasionally - my daughter drives it. Runs 15.0 in the quarter. Weighs 4000 lbs with me in it. Has the original 383 with 8.9:1 compression, Holley Street Dominator intake with a Holley 750 double pumper carb Cam is 0.474 lift and 233/240 duration (intake/exhaust) @ 0.050.

Suggestion on what to do with the distributor? Its a 1990 vintage Mopar Performance vacuum advance with Pertronix ignition.
