Cool list.
Two things I noticed:
1) A 440 Cuda ran 14.01. Pretty darn close to 13's!
2) A rambler 390 ran 14.2. That would have put it fifth in this whole list of cars. Not too bad!
My father-in-law had been building high performance engines for almost 60 years - he owns a speed shop. Anyway, he said that the machining work on AMCs was by far the best of any American manufacturer.
