Holley LS Fest - Is there a class for tubbed and narrowed

I was looking on Holleys site and they have a Rumble (Index) class. The rules for that class say:
"Vehicles are required to be stock appearing and stock bodied"

I have a tube chassis 69' camarro with 33x14 slicks on the back that I am putting a twin turbo 4.8L in. So does stock appearing allow for narrowed rear ends and big drag car slicks? If not what class could I run? Will they have just regular old braket racing there?

Great question, I'll ping the guys.

I am half shocked about this. It seams to me that more and more LS motors should be making there way into old bracket cars and pro street cars. I just want to know if I haul my car to Kentucky can I actually race it at LS fest. Assuming that I get done and ready to go by then.
