My suggestion for rules and I have no dog in the fight because I run a sbf in my dart
1/8 Mile, Heads Up, .400 Pro Tree, 32 Car Field, Sportsman Ladder, Lane choice goes to higher qualifier first round, and then the faster car from previous round.
Rear Tires 29.5" x 10.5 non W or 315 drag radial or smaller
Front Chassis/Suspension
All door cars allowed must add. 100lb for tube chassis car
Rear Chassis/Suspension Any type rear suspension allowed. Engine Any engine combination allowed. Motor plates and solid mounts allowed. Mufflers required for all cars except turbocharged entries. All nitrous bottles to be safety vented pop off to outside the vehicle.
Transmission All allowed must add 50lb for clutchless type
Basic same rules as outlaw without the frame rail factory location stuff. Because with a once or twice a year race who wants to build a car for it and many mopar racers would not make it if those rules are in and if everyone weighs the same it is not that big of a deal
