Here is my take on the deal, and I've posted this before. Pro Stock has lost it's fan appeal, at least in my opinion. What made it fun for me, had to do with direct manufacturer involvement for the most part. Bob Glidden Ford vs. WJ Olds, or Reher & Morrison and later all them vs. Wayne County Mopars. That really made the show, and that was hyped on TV as well. In my mind I can still here Steve Evans talking about a "Classic Ford vs Chevrolet battle!" As the cars were staging, and it truly was. Of course we also had several other great Pro Stock drivers but I'll just use them as an example. The rivalry was a big deal between drivers and manufactures. Now days it's all Camaros, and the rivalry is which Millionaire / Billionaire kids and grand kids are pissed at whomever because of an engine lease deal gone bad, or changed hands. I still pull for Greg Anderson and Jason Line for being old school guys from my home state.
How do we get fan appeal back? I don't know. I think it's too far gone, and there's no turning back no matter how many races they run, or what rules they change. The class is too expensive, the cars don't look that much like factory cars, list goes on.
I think the factory stock showdown stuff is pretty cool. They are very much stock appearing cars. I think my next race car might just be a 5th/6th gen Camaro.
You can find a used Gen 5/6 SS V8 Camaro for $25,000. Put a nice set of Weld wheels, appropriate rubber, a nice converter, and a tune, and you will run well into the 12's if not the 11's for $30,000. You could put that car next to a FSS car and darn near not be able to tell them apart without opening the hood or looking underneath. I think that is appealing to fans, and racers alike.
