A 9.80 index makes no sense. The supercharged CJs get to weigh almost 400 lbs less in AA/S and that's with a 10.00 index. I would think around 10.40 would be closer.

If those are the rules they decide on, I think the 427 COPOs may be hard to beat if someone gets a good motor built by Indy and they can get light enough.
