Well, I've got the Gen 3 392/545RFE package in my 70 Dart and I love it. I go down the road @80mph and I get 18MPG. I'm about to start a 68Charger build and was going to do another 392 crate package with a NAG1 this time, so I'd really be interested in your 392 package if its going to be available soon. Let me know.
