Thank you guys, most of it is luck and yes physics and trusting the car as with the weight set up it will go straight provided air in the tires is equal and nothing under one tire (oil/etc.). In that picture it was about the 10th pass on a new Aluminum block 572" wedge that I had just installed so quite a bit more torque then the previous 505" high compression race gas motor and about 100 lbs less weight than I had previosly ran. It was almost on the rear valance when I left and started coming down at a controlled rate but when it hit 2nd gear it came back up again and ran about 300' out before coming back down. It was an elimination round so I road it out, you don't want to lift unless not going straight as you risk hurting the chassis. After that run which I lost I went home and installed wheelie bars and also a MSD Grid ignition system. That Grid ignition is amazing in that you can tune the car with a laptop and take ignition timing out of it to soften the hit. I take about 12* degrees of timing out and ramp it back in in about 1.5 seconds so it really is effectice traction control and keeps the 60' times consistent. I added it to our road runner as well as it's running on 9" drag radials. Basiclly it takes about 3/10's out of the performance (9.33 instead of 9.03) but what you gain on consistency is huge. So the wheelie's are just part of the chassis set up and typically consistent given equal track prep.
Here's some old bad footage aftre the wheelie bars/Grid:
