The motor in the Mustang has a normal timing curve and idles about 1200 but doesn't "like" anything but "punch it I know the road!".... so I have no clue about street driving your monster race car -- 'cause I just wouldn't do it. :>)

I know that the TOTAL timing was set at the dyno --- but the curve is every bit as important.

That's now how Mike rolls with his dyno. He gets it running good and safe and then says tune it in the car. Many people tune on a dyno but not Mike. He says too many conditions (loads, etc) change from dyno to car so it's a wasted strain on the dyno.
This is just getting a base curve to start out.
Plenty of people (like you in your tracky car) just run a locked out full advance setup just fine. We ran it on my last motor and it was great for 2 years.
MSD probably had not invented the programmable 6AL-2 box back when you were dealing with your coilus interruptus.
