First Time Drag Racing!
Sounds healthy, very nice first outing! What cam do you have in it? Just curious because it would probably go a little quicker with lower shift points. Strokers don't need anywhere near the RPM as standard stroke small blocks do to make the same power. For example, I can shift my 410 anywhere between 6200 and 6500 and it will run the same number. If I shift at 6000 it looses 0.01-0.02.
The launch vid looks like you need to get the front end looser to get better weight transfer. When you get some more suspension travel that thing should knock a few more tenths off the ET. With the MPH, you should be able to get 10.7's no problem. Good luck.
