Question 1) Yes, you have picked up on a big problem.
Question 2) maybe
Q1) BB drop in the 50s is good. Anything over 60 is going to start to cause problems.
You have a lot more drop there, which is not unusual for the type of bike you are riding. So, the generalized answer to your question is no, you cannot use that on the track.
As you have noted, there may be some mitigating questions.
What type of track are you on, specifically what is the angle of the turns? If you are on one of these mini-NASCAR asphalt conversions or a long shallow 333+ meter track, it is going to be less of an issue. If you are on a track with 44degree banking, you are going to have pedal strike unless you are experienced and limit what you do.
Q2) To answer your other question, sure, if you donít go above the black line (i.e. single bike time trial events at the black line only), and maintain speeds of over 20mph, you can probably get away with it. The real question is will the track officials let you do it? I doubt it, but the only way you will know for sure is to ask.
One quick test is to take your bike to the banking, and hold it vertical with the outside pedal down. Does it hit? Answer: yes (on most tracks).
