Me I think the rules should be change some mainly the carb & intake rule but most all "crate motor" cars are fine high quality cars.

I really don't understand "why" there's such a problem with the crate motor class. The allowed motors all have technical specifications, just like any other engine. Due to the vortec heads, you are somewhat limited in the intake department. That leaves the 750-850 cfm carburetor, typically a double pumper Holley, that seems to be a rub.
The chassis, interior, fuel system, all have to be built like any stocker combination. Big difference I see with IHRA, they allow roller rockers, 10.5 inch tires, aluminum driveshafts and deep sump oil pans. that is pretty much all stockers, unless you're building a crossover car.
I guess to pose a question. What, today, really defines a car as "stock"? Is it compression ratio, because you're allowed aftermarket replacement pistons. Is it cam specs, you're allowed to manipulate all but the lift. Is it intake and carburetor, you're allowed replacement carbs for some that are no longer available. Many cars are running transmissions that were never offered for those cars, ie; metric transmissions in older GM's.
I'll freely admit. I wasn't real enthusiastic about the class initially myself. My partner convinced me to sit down and read the rules regarding the class. The concept suddenly became very clear, these motors very much resembled the same kind of street motors we were building 30 some years ago. A motor, the SBC, that I understand, with a Holley carburetor. The car stilll has to be built, tuned, sorted out and run below it's index.
I know another argument I've heard, too many classes. A class of this nature, might allow people to get their feet wet.
Just a few late nite rambling thoughts,
