Why do Mopar Engines Have a Different Sound From Chevys and Fords??

I always used to say a B block Mopar sounded like two Harleys running.
Chevies and Fords definitly DO NOT sound like that.

Also the small block Magnums (92-03) also have a very distinctive sound.
It's very easy to tell when one of those starts up.
Even my wife can tell and routinely comments that they sound "bad ***".

I love them both.
