putting a ford 5.0 in a 72 Dart

I've been by-passing this thread for a while, but chuckle everytime I see it, reminded of the time a customer at my business, while walking behind my Dart, asked how he could get his Fex body to sound like my Dart.
I told him he couldn't afford it, he asked why .
I said " cuz I'd have to put Mopar running gear in it " !
Chuckle.
Sorry .
