Yes there is 8000&8500lb 2.6 and Outlaw class. The 8000lb class in 2.6 and outlaw is what is paying out the $1000 on down. Reason for 2 different weight class gives you more than one pull for the day if you choose to. Most people don't weigh that heavy in those classes. In workstock 8500lb will allow the cc fords to pull since most are over 8000lbs.
Outlaw is like a run what you brung class ie: twins, cut tires, open driveline is allowed. Anything that is bigger than a 2.6 turbo will pull in this class.
