INDIANAPOLIS – Bonus nights of AMSOIL USAC National Sprint Car Series racing have been added to Independence Day week, kicking off the month of July in spectacular fashion.

On Wednesday, July 1, the 50th annual Tony Hulman Classic comes to the Terre Haute (Ind.) Action Track, continuing a tradition that began in 1971 on the famed half-mile dirt oval at the Wabash Valley Fairgrounds.

Furthermore, a date for the series has been added to the Bill Gardner Sprintacular to make for back-to-back nights of racing for the AMSOIL USAC National Sprint Cars and the Midwest Sprint Car Series at Lincoln Park Speedway in Putnamville, Ind. on July 3-4.

The Friday, July 3 event will be a full-points event for MSCS and will award 50 appearance points to all competing licensed AMSOIL USAC National Sprint Car drivers and teams toward the series championship standings.

The MSCS format will be utilized with group qualifying and a drawing to be held after the heats to determine the exact number of cars to be inverted at the front of the feature.

The Saturday, July 4 event at Lincoln Park will be a full-points race for both the USAC AMSOIL National Sprint Cars and the MSCS sprints.

USAC’s format of single car qualifying, with the top four transferring from each heat race and top six from the semi-feature to seed the feature starting lineup, will be used.

Meanwhile, the series has announced the postponement of a pair of AMSOIL USAC National Sprint Car events, the June 27 race at I-96 Speedway in Lake Odessa, Mich., and the July 9 event at I-80 Speedway in Greenwood, Neb.

Additionally, earlier this afternoon, both the Illinois State Fairgrounds and the DuQuoin State Fairgrounds announced the cancellation of their annual state fairs.

However Track Enterprises, the promoter of both the Bettenhausen 100 and Ted Horn 100 USAC Silver Crown events at both one-mile dirt ovals, is working with each fair manager regarding the possibility of still holding both events this season.
