71 Dart / 5.9 Magnum / Procharger

What timing control are going to use.
I've got an MSD pro billet distributor and 6AL box with a blaster coil. I'll be running a water injection kit to help cool the air charge and hopefully keep it from detonating. We'll see. The water injection will kick in at 4 lbs of boost. I may have to go to some sort of timing control later on, not sure
