Co-driver R. J. Valentine announced Lally's plans to race in the NASCAR Busch Series, possibly with support from TRG during the broadcast of the Grand-Am Rolex Sports Car Series GT Race at Iowa Speedway on July 14, 2007. Lally raced the No. 47 Clorox Ford Fusion in the NASCAR Busch Series road races at Circuit Gilles Villeneuve on August 4 and Watkins Glen on August 11 as part of a partnership between TRG and Wood Brothers/JTG Racing. He finished 29th and 10th respectively. In October 2007, TRG purchased the assets of Darrell Waltrip Motorsports' Craftsman Truck Series team, with Lally serving as the team's driver and United States Army Reserve sponsoring the No. 00 Toyota Tundra.
