Drag racing classes

Just checked the site it’s just gives basic car safety rules, but no mention of classes.

For starters I’ll probably run in the 12 somewhere. Gonna run the 380hp 5.9 Mopar create engine I got in a gutted Jeep.
When they post the schedule there should be some clues. And even if the car is not done, it may be worth visiting the track to observe and talk with folks.
