I've mentioned 'Pro Camaro' but that's not really the problem. IndyCar is doing well, F1 is doing spectacularly well and those cars are just as unilateral as Pro Stock cars. The only thing that differentiates them is the paint and a few are running Chevy engines which fans don't give a rat's patootie about.
Pro Stock is more of a victim than a perpetrator. Victim of the race Sunday/buy Monday mentality of 1970. Victim of crazy expense and the technical skill to be competitive. Victim of personal devices, namely, the almighty cell phone. TikTok rules, not NHRA. Victim of no longer being exciting enough to grab and hold the attention of the average fan. The big tire/small tire no-prep stuff does well because it's comparatively cheaper, less technical, it often offers huge purses and those competing/attending tend to be much more hardcore drag racing folks than your average IPhone champion.
Major props to Del for thinking outside the box. What's not to love about a new combination and a 10,000hp margarita mixer? LOL But I seriously doubt it will save TAFC - if for no other reason it's a lot more expensive but with no additional return on investment. And all fans are going to see is cars that look, sound and run 40mph slower than the cars they just saw run 30 minutes ago.
