first time to track what would you bring?
I would suggest a generator and charger or a fully charged spare battery cause my car always seems to run out of juice after about 5-6 passes. Bring enough fuel. Bring some basic tools like what you will need to change the timing and replace that battery. The car should be ready to run and if something breaks you will probably be putting it on the trailer or another racer may have what you need. So bring cash for that eventuality. It is hot out so bring a couple sweat towels.
The most important thing is to have fun and keep it out of the wall. There are some threads here and elsewhere on drag racing 101 with pointers on how to get down the track. Keep a good attitude and make friends with not only the other Mopar guys but even chebby and ferd guys too.
