First time at the strip for the Dart, results and what I should do for next time?

So about 20 yrs after I built the engine the Dart finally made it to the track a few weeks ago. It was busy and I only got two runs in. First run car stalled after the burnout I got flustered rushed everything left the line sideways ran something like a 14.2. Second run slowed down didn't get a great burnout left the line just above idle still spun but not as bad as the first run, spun again a little on the 1-2 shift, 13.08/107mph, 2.125 60ft.
Here's the combo 69 Dart, 360/727 8-3/4 3.91s. 360 has Ebrock performer heads no porting/Hughs Cam .535/237 Intake/.540/243 108. Airgap RPM /Holley Street avenger 750 vac sec./~10.5:1. T/A converter 3500 stall. Pinion snubber/5 leaf springs/basic kyb shocks/.990 t-bars. /225 drag radials.
I roller through the water stepped on the manual brakes (no line lock) the tires would spin but it was hard to keep the car from rolling forward too fast.
So, I plan to go back in a few weeks- what changes would you make and why?

Thanks for any help/suggestions, as I started with I've been out the hobby for years finally getting going again.
