nascar's part choices are not connected with best for the job. They're what they are for a variety of verifiable control and safety (not making too much power) reasons so the races are less about the cars and more about the drivers.

You can tune a carb to run well in all weather, and if you know what you’re doing there’s nothing wrong with them.
Your idea that they’re not great probably comes from just bolting it on and wondering why it runs like crap, and then trying to start a cold one in the middle of winter by pumping the accelerator 50 times
A good carb tuned properly is every bit as good as fuel injection. Just not as good on fuel or as low in emissions.
