Drivability means more than can it do it . My Swinger has a 408 with a 108 cam and my Barracuda had a 360 ( soon to be a 408) with a 112 cam . The Dart can drive in town but it’s not near as smooth as my Barracuda. I am sticking with the 112 in the new 408 because most of my drive time in it is below 3500.
