If we want to take an alternative perspective:
Why dont we get midgets back on smaller race tracks where they belong and HP isnt the ultimate factor!
If we use Grundy County Speedway, IL (1/3 mile ) for example, UMARA home track... I can tell you that a -12 head, 155 esslinger, mopar, any older gen motor is still extremely competitive and have won alot of races there. All you need is a good handeling car and a driver.
I think NASCAR has proven this theory true by racing at places like Bristol where it's proven you can go faster by detuning a bigger motor.
Big Motors are only good on Big race tracks which often times = a boring race for the fans.
Just another perspective
