NHRA will not be bothered with Pro Stock that requires weight breaks, factors, or other adjustments.

The 500 cubic inch 2350 pound version of Pro Stock is actually the most healthy and most sustainable over time.

Some of the money can be negated by common sense rules. Take them back to a 14"x32" slick. A body template rule with reasonable scoop and spoiler limits, which will also make them look like factory cars. Modify the EFI rule and take the throttle body size down. Get rid of some exotic materials.

Factory Stock works now because it is something like the old muscle car wars, where the customers are absorbing the costs of development to a large degree ($100K per car makes it somewhat affordable to amortize it when most of what changes is just the engine). Even better, no insurance problems or government safety and emission regulations.

As soon as you take that to a professional level, the customers don't absorb so much of the cost, they expect parts, cars, and development help. Not only that, they expect new combinations to beat the factors when weight breaks and factors get involved. Not to mention NHRA then has to make the three of them happy with factors, and then you have the nightmare of factoring small engines against big engines, supercharged against normally aspirated, etc.
