I noted this video today that was posted on the Chrysler 300 Club Website. A very well-done car.
To me, the 300L was more "ordinary" than the earlier models of Letter Cars were, BUT it's still what it is, no matter what. Still had the HD suspension calibrations, just no really special engine as the 413 Long Rams were. The expansion of the Interstate Highway system kind of made the added mid-range torque of the "ram induction" not really needed anymore as relaxed cruising tended to replace "two-lane blacktop passes", as I recall. The larger 440 in '66 resulted in more torque, so the 1966 300 2-dr hardtop with the 440TNT motor and HD suspension (which was tested by CAR LIFE magazine) was dubbed "300M" by them, although not a real letter car from Chrysler.
By 1966, the performance-bearers had become the intermediate-sized cars with 440s and 426HEMIs in them. They did well. They were more about 1/4 mile acceleration or NASCAR as the Letter Cars were about high-speed driving for long distances. In comfort with style, class, and acknowledged race-heritage power (which CAN include every B/RB Chrysler V-8).
Just some thoughts,

Awesome car and it shows me once again how "ordinary" five years later the the Chrysler 300L was
