These are basic rules - got them from I29 Dragway website. From my memory and review of rule book when we set up our car, this seems right. The actual rule book takes a bit to read and find specifics.
Street Cars The following items are required for a vehicle and driver to pass tech: Good tires, a solid battery hold down, radiator overflow reservoir, functioning neutral-safety switch, seat belts, and a valid state driver's license or NHRA competition license for all participants. The driver must wear long pants, closed toe shoes, and a shirt.

“Unaltered” is the wild card. Of course throwing a blower on one is obvious. But, technically, what about stickie mickies on a Demon? What about a different cam in a ZR1?
If you read that article (and some others) I think they made this concession: Newer cars are designed much safer, people want to run em all out on the track and they want people in a declining sport and so many cars now can run low 11s and better stock. Not a lot. But many.
