It's not often that the champions of the two major series for racing Nostalgia Funny Cars get the opportunity to race in the final round of the last race of the season. 

Jason Rupert entered the California Hot Rod Reunion having won the IHRA Funny Car title a little over a month ago. He was the No. 1 qualifier from start to finish.

Kris Krabill earlier in the day clinched the NHRA Heritage Series Funny car crown. 

The following are the sportsman final results from the 25th annual California Hot Rod Reunion in Bakersfield, Ca.

Below are the round by round professional results from the 25th annual NHRA Heritage Series California Hot Rod Reunion.

Weather delays and an incredible car count at the Professional Drag Racers Association (PDRA) Brian Olson Memorial World Finals pushed the third qualifying session well into Saturday evening, but the wait was worth it for Switzer Dynamics Pro Nitrous presented by MoTeC number one qualifier Chris Rini. The New York native ran a career-best 3.694 at 199.26 mph to earn his first low qualifier award with the PDRA.

Late rain showers and falling temperatures forced race officials to postpone Friday’s qualifying action at the Professional Drag Racers Association (PDRA) Brian Olson Memorial World Finals at Virginia Motorsports Park. The inclement weather set in during the middle of the second qualifying session for Top Sportsman, which featured a record 74 cars attempting to qualify.

Growing up in Canada, hockey was a way of life for Jeff Arend. He competed in the sport from age 6 to 17.

Arend, however, was intrigued with motorsports and eventually took that path.

Jack Beckman knows how to win races. He also knows how to capture a world championship.

Still, the veteran nitro Funny Car driver from California also knows adding a second world title to his resume this year is a little far-fetched.

Keith Haney and his Keith Haney Racing team are likely done for the 2016 season after Haney decided not to race "Notorious" in the PDRA World Finals this weekend at Virginia Motorsports Park.

Haney has driven the Lucas Oil/RacingJunk.com Chevrolet -- nicknamed "Notorious" -- in the Pro Nitrous class this season, but he and his team are taking the weekend off.

The Professional Drag Racers Association (PDRA) will stage its final event of the season this weekend at Virginia Motorsports Park and among the awards at stake is $5700 in fuel credits posted by VP Racing Fuels, the Official Fuel of PDRA.  The awards include $1000 to the champion in each of the Pro automotive classes, $500 to Pro Extreme Motorcycle, Top Sportsman and Top Dragster champions and $100 each to the Junior Dragster and Top Junior Dragster champion.

In addition to gift certificates in these amounts to be awarded at the end-of-year banquet, each class champion also will receive a VP Racing Fuels Championship jacket, according to Mark Ticen, VP’s Director of Race Fuel Sales.  “It gives us great pleasure to provide these awards in recognition of the hard work and dedication required to achieve these championships,” Ticen said.
