As I remember it, the AMA (Automobile Manufacturers of America) required each make to submit detailed specifications of every car they built. The NHRA got that info from them and that's where the detailed engine specs, weight, etc. came from.

By this time in my life, I run into hazy memory at times but I seem to remember that when the imports gained a big chunk of production, the AMA ceased to exist - because of the "American" in their name now only produced only part of production instead of all of it. Then again, maybe they still exist and dropped the requirement for documentation.

I'm sure you remember it wasn't always that the manufacturers had to apply to the NHRA. Only when it was after the start of model year production (Cobra Jet, etc) and that year's book had already been received in Glendora.
