I found another track test of a 375hp 440 in a '69 gtx automatic 3.91 gear car. best e.t. was 13.98 and best mph was 103.80. I consider this performance to be more of an exception than common place. I remember back in the late '60's, when pure stock racing really was pure stock, 375hp 440's would run in the lower half of 14 sec bracket. exceptions to that would be 14.00's to 13.90's at 100mph.

on another note here, who was the first to coin the phrase 6 bbl? ford in 1962 with their 3 carb 405hp 406.
