MEMPHIS, Mo. – The Dart Iron Man Challenge invades the Scotland County Speedway in Memphis, Mo., this Saturday, June 19, for the third round of action for the newly-formed series for full-fendered USRA Karl Chevrolet Stock Cars.

In all, 14 dates at 12 premier speedways throughout Iowa, Minnesota and Missouri dot the calendar for the 2010 campaign.

The ultra-competitive and exciting USRA Karl Chevrolet Stock Cars will be teaming up with the undisputed heavyweight champion of Modified racing this season to create the ultimate feast for the action-hungry dirt racing fan as the Dart Iron Man Challenge will accompany the popular USMTS Casey’s General Stores National Tour at each of the 14 events.

Made possible by support from Dart Machinery and Allstar Performance, all races will pay $600 to win and $125 to start the main event with 21 or more entries in the field.

The ten-race points fund will carry a $1,000 top prize with the tenth-place finisher earning $100.

Dart will award a $75 certificate to the winner of each event and a $50 certificate to the ninth-place finisher, and each event will have a qualifying format similar to the USMTS, with heat race passing points determining the “B” Main and “A” Main line-ups.

In addition, each race will award national points in the USRA Karl Chevrolet Stock Car division of the American Racer USRA Weekly Racing Series where the national champion will earn $700.

On Saturday, pit and grandstand gates open at 5 p.m., hot laps begin at 6:30 and racing starts at 7 p.m. Along with the USMTS Modifieds and USRA Karl Chevrolet Stock Cars, rounding out the evening’s racing card will be USRA Karl Performance Parts B-Mods, USRA Hobby Stocks and Four-Cylinders.

Race fans can pick up $2-off coupons at Casey’s General Store locations in Edina, Kahoka, Lancaster, Memphis and Queen City, plus north of the border in Bloomfield, Iowa. For more information or to find the location nearest you, check out www.caseys.com.
