K and L have been like that for years and there has never been a reasonable explanation for the disparity. We tried to get it changed as far back as 1983 but no dice.

Wouldn't this ADR Challenger be in a Factory Stock class?

When those who campaigned for AA/SA and AA/S were asked by NHRA officials (I won't say who) what the index should be, everyone I know who answered agreed on 10.90, which was, at the time, 0.35 and 0.40 quicker than the next lower classes. The idea being to let people go out and turn the cars loose. However, that was a year or two before the indexes were lowered by 0.30 across the board. The AA classes were requested by and for people running traditional big HP cars, such as the Street Hemi, the 427 Fords, and the 427 and 454 Chevrolet engines rated at 425HP or higher. However, the indexes were lower after the new factory race cars were introduced in the regular classes. Well, we got what we asked for, and we've lived with it. Yes, it would be nice to see the index for AA back up around 10.80 or 10.90, but it is what it is.

I agree with Bruce on this one. Let's look at the facts.

Using Nitro Joe stats, when you look at the quickest runs in all Auto Trans Stock classes you will note that the AA/SA cars have not been able to run as far under the index as all the other classes.

When you look at the NHRA HP ratings of the cars in AA/SA, they range from 381 to 450 HP. That means to jump from A/SA (11.00) to AA/SA (10.60) these cars can remove anywhere from 381/2 = 190.5 lbs. to 450/2 = 225 lbs.. For that weight advantage they have an index that is 0.40 seconds quicker.

Who is willing to give up 0.40 seconds for 200 lbs.?????? Raise your hand !!!!

I think 11.00 - 0.25 = 10.75 would be a lot more reasonable.

Take a look at the cars that have jumped around from A/SA to AA/SA. They have not been able to run as far under the index in AA as they can in A.

I was against slowing the index ,if its what is best for the class then I vote to change it to 10.80 . I also feel hat we should have 7.0# class that way the 6.5# cars can race as well. leave the 10.60 index for the 7.0# cars
