LOVE to see MOPARS at the track, especially surrounded by..or in front of other makes. I ran a 727 for years behind a 340 in both autocross and road racing and while I had several fixes for keeping the trans fluid where it belonged, the best, and simplest was removing the dipstick entirely (when racing) leaving the tube, and capping it with rubber cap (like the kind to block off unused heater hose) I also used a worm style clamp for extra measure.

Not sure what you have for brakes, but heat may be a big issue with yours if they are factory. A somewhat easy/affordable solution would be better/aggressive pads for whatever calipers you run. My car is now dual purpose and road and track (fulfilling the R/T legacy) and I spend some time before events changing brakes, shock settings, alignment settings, ride height, tires etc, and the car becomes completely different on track than on the street. A little planning and a few minor tweaks can make a street car a pretty decent track car.
