GTX John,,,,,,you said it,,,,,no else did,,,,,,,,
Had to look, but the 1964 A/S and A/SA Class Records
A/S,,,,,,,,,12.56 @ 112.99
A/SA,,,,,,12.80 @ 111.10
No 426-S 'Street-Wedge' cars running near that in Stock...
Fast-forward to 1970 where they would fit in E/S or E/SA.
E/S,,,,, 11.97 @ 115.83
E/SA,,,11.94 @ 115.22
