I never get tired of listening to this...
I used to love the sound of the factory 67--70 Mopar performance packages, 340, 383 RR and 440, and of course we don't even have to MENTION hemi LOL
I can still remember AKA my 69 383 RR or the 6 bbl 70 car
"Sounds like you have a cam in it."
"JUST FACTORY!!!"
