They don't use off the shelf boxes. None of them do. And what the Pro Stock guy get and use you can't buy.

As I slowly add to my collection of ignition boxes to test, I'll get some MSD junk and see what it does as far as retard with RPM. I may even test some coils, but I know, for a fact that most of the early (and who knows how long it went on) Blaster and Blaster II coils were substandard.
That's why I'm doing the testing so I will know for myself.
