Hello 66 Dartman. So I am heading back to Tennessee in 4 days to pick up my first project car, a 66 Dart base model for $950. I like the back lines on this model, sort of the last of it's kind. But I want to give her some muscle, mabey a 340 swap and all that goes with it. Do you see any prohibitive issues converting from automatic to 4 speed on this car?
