How are today’s as/ah cars different

Today's cars aren't even close to what the factory envisioned and what NHRA thought a "super" "stock car" should be. As mentioned, tires, suspension, cam, head, intake and suspension mods & rule changes have all contributed to the 2+second reduction the OP mentions---- not a good idea, IMO as these cars are now essentially P/S cars or at least Modified Eliminator cars that most can't afford or even have the ability to maintain IF they could afford one. A bad deal all around if you ask me...…….
