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

The 1970 340 ci four barrel Dodge Dart Swinger I drove as a 16 year old in 1974 to high school. That car, even with the three speed auto, was as balanced and fast a car as I ever drove. Later when I drove the police package 440s for work as a PSP Trooper, they were great in a straight line but awful in curves.
