Help me find the umph in my 360

Might have been the quickest. I know they whooped the Corvettes of the year. Pretty embarrassing for Chevy.
Kind of like the Buick Regals and Grand Nationals that were quicker than the Corvettes. A 3.8L V6 whupping a 5.7L 'vette sure soured the Chubby guys milk. Chubby's flag ship getting whupped by an old man sedan.
