Early vs. Late dusters

Not snobs, I look at the raw material and what I want to end up with. Is the 360 cobbled in there? I would not touch it, don't like them anyway. Is he mature enough not to get in trouble with a 360? How much gas will it use? I can tell you my son's 73 Dart 4 door didn't get the 4 barrel, cam, and dual exhaust till he was older than 20. Even so he admitted he was running someone in Baltimore somewhere around 100 mph with the original 318 2 barrel. I also like the person who said he should drive it and see if he liked it. I've run them all and had a 71 340 4 speed Duster and a 72 225 auto Duster. I like the feel of the early Dusters. Value does not enter into my decisions.
