Note here, NHRA refactored those cars too. I think 345 was the original re-factored rating.

Lets not forget how the weight breaks just happend to fall for some scrub engine body configurations. To the third decimal point.

How about a '57 Ford 2 dr wagon with a shipping weight of 3600 lbs?  With a 300 horse engine it falls exactly at 12.0000 lbs/cu. in.  That's why Gordon Payne (and others) used them, besides they had a little more weight in the rear than a Custom 2 door.
