Before that, the cars were actually weighed at the track and the class break calculated then. It doesn't take much imagination to see why that didn't work.

So does NHRA use curb weight or shipping weight on their classification sheets? Because in one particular instance, there is a 455 lbs difference between the two weights and NHRA has the curb weight listed as the shipping weight on the classification sheet.
You can see why it is very interesting to see what NHRA actually uses for classification purposes. This would move this particular car up 2 classes.
