Sorry, I have to disagree. I have both. a 69 340 dart and a nice 68 383 Dart. They both run very well. but the difference is an Idiot can race a 340 Dart, just step on the pedal and go. but it takes skill to launch and race a 383 dart. My Brother was a service manager at a dodge dealership in 1968, and the 340 was nicknamed the "baby hemi'.
The records speak for themselves, just look at the drag records from 68-70.
