My GenIII Hemi uses a crankshaft sensor, so no distributor. The MSD Hemi-6 controller that runs the ignition is solid state. The curve is programmable as is a 2 step, but there is no stage retard feature. I think I'll just loosen the Caltrac bars a little and maybe tighten the torsion bars up a little to slow the weight transfer, along with a shorter burnout. I've already bumped the timing up 3 degrees from normal.
