After watching the video i can say two things. You need to practice launching much more and you need to get rid of the bilstein front shocks, they are far from optimal for a drag set up. Also your car is very noise heavy with an iron block and blower, 175 pound springs would be a little light for your nose weight id put a 200 14" if it was my car and i drove it on the street as well . I think the 250s your running now could get by with a proper strut but would not be optimal for drag racing, i know this from experience. That car just needs a few tweaks and a good launch and youll be cutting good 60 fts. My stick car was lowered 2 inches and still cut low 1.5s on nittos and it was all from sorting out my front end. I would keep practicing as well, that will help you learn your car. Lots of good information in this thread im just not sure if much of it would apply to your car, but that is just my opinion.
