First time at the strip for the Dart, results and what I should do for next time?
Frankly, you don’t have enough runs on it to know what if anything needs changing yet.
Get to the point where it will repeat within a tenth or so before making any changes to the combo.
I concur with the line lock suggestion.
At 107, mid 12’s would be no problem....... if the 60’ times come around.
Once you’re at the point of pretty reliable repeatability....... then you’re ready to start making changes.
Unless the car is dead hooking....... the first place I’d likely go is the T-bars and shocks.
If the car won’t hook well enough to get the ET’s within a tenth or so, you may have to start looking at the T-bars and shocks sooner rather than later.
Like the ET’s....... you are also looking for good repeatability from the 60’ timer.
