Although the final finishing order is yet to be determined, the Funny Car class is the first to set its 10-driver field for the Countdown to 1 playoffs that begin after the next race, the Mac Tools U.S. Nationals. A combination of round-wins by Jack Beckman (pictured) and Mike Neff and early losses by Del Worsham and Bob Tasca III at the Toyo Tires NHRA Nationals sealed the field.

The Funny Car drivers in the Countdown will be Tim Wilkerson, Tony Pedregon, Robert Hight, Cruz Pedregon, Ashley Force, John Force, Gary Densham, Ron Capps, Beckman, and Neff.
