I consider the 1950s as the most important. This was before Chrysler started dropping Marques (started in 1961 with Desoto). It was also when the legendary performance motto became popular with the hemi, was the inception and creation of many of Mopars most famous engine families.

 

1964 - 1970 inclusive for me, The 60's.

 

I'll Take the 5th

 

The one with cars👍

 

I'd extend those years by a couple, 1964-1972
