The 1971 purple R/T Challengers:
One is mine... original Plum Crazy big block 4 speed car.
The other is my wife's... original green R/T Challenger that the wife wanted purple(she had her's first) now running a 440 Sixpack with automatic.

The 1973 Challenger I bought 30 years ago at age 15, it was my first car.

I had a 72 'Cuda that I sold to my brother and currently have a camera shy 1970 'Cuda(original 440 car) that's buried in storage. Too many other old cars over the years to begin to count.

I'm not a "Mopar only" guy and have had quite a few other brand toys.

Your Challenger is a very impressive running car, I would like to try a boosted big block Mopar someday but I have zero experience with them.
