MARSHALLTOWN, Iowa – Heavy rain soaked the Marshalltown Speedway Tuesday night, forcing officials to cancel the evening’s remaining events which inlcuded the feature race for the Sart Iron Man Challenge for USRA Karl Chevrolet Stock Cars.

Nathan Wood and Damon Murty captured heat race wins for the 18 entrants.

The race will not be rescheduled. All drivers in attendance will be credited with 50 points.

Just two events remain in the 2010 campaign this Wednesday and Thursday, Sept. 1-2, at the Southern Iowa Speedway in Oskaloosa, Iowa, and Highway 3 Raceway in Allison, Iowa.

Fifteen dates at thirteen premier speedways throughout Iowa, Minnesota and Missouri dot the calendar for the inaugural campaign for the Dart Iron Man Challenge, which accompanies the popular USMTS Modifieds at each event. 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.

Each driver’s ten best points-earning performances will count toward the final year-end standings with a $1,000 top prize for he series champ and the tenth-place finisher earning $100. 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.

A USRA license is not required to compete and/or earn points in the Dart Iron Man Challenge, but only USRA-licensed drivers will be eligible for points funds in either the Dart Iron Man Challenge or American Racer USRA Weekly Racing Series.

USRA rules will apply at each event. Drivers are permitted to utilize the Rochester, Motorcraft or 1¾ Holley 4412 open carburetor but must be run with the Edelbrock Performer (Part #2701) or Weiand X-CELerator (Part ##7541) intake manifold. These intakes must be stock (no porting allowed). The 4412 carb must be stock and must be 1-11/16. For conforming to IMCA rules, the 350 carb is allowed with a 2,800-pound weight rule. Any driver running the 604 crate motor is allowed the 4-barrel carburetor.

Production and camera crews will be on location at remaining 2010 events as they record the USMTS action for the upcoming Dirt Knights TV show. Dirt Knights will be an on-going dramatic series of one-hour programs that will air twice a week for 13 weeks. The much-anticipated TV show is set to debut in January of 2011 on the VERSUS cable network - the fastest growing cable sports network in the nation, which reaches more than 75 million households.
