Watch the rules for totb as well as time attack. I remember there being rules about not modifying inner arches so that tubbed drag cars could not run. You should check these before you start if you intend to run it. I'm sure they would find a way to stop you if they wanted though, but unlike time attack the boys running it usually seem really up for seeing different mental cars
And yes there are probably 10s of cars that are in breach one way or another but just warning you
