What was the ultimate "normal production" factory A Body?

Clearly,

The 1969 440 Cuda. I had one, and it was 'uncontrollable on the street'.

1) 1969 440 Cuda (M-Code)
2) 1969 Dart 440 (M-Code)
3) 1968 Barracuda 340 'Formula S' 4-Speed (The 1968 4-speeds had the bumpier camshaft)
4) 1965 Valiant V-200 273/235 HP (The car only weighed in at #2712 lbs.)
5) 1969 Dart GTS 383
6) 1970 340 Duster
