Fastest Duster on stockish suspension?

Yeah it's a bad beeotch. He's indexing like 6.50s in the 1320. That's haulin the mail with leaf sprAngs.

i drove down to lights out last Feb at SGMP hoping this car was there, sadly it wasnt.
Somebody told me it was gonna be at Orlando a week or two later.
That's when i noticed no leaf spring class, not sure bit the car might run Limited now, not sure if its competetive.
