2007 Lenox Industrial Tools 300

The event served as the eighth race for the new Car of Tomorrow and its first race at NHIS.

Dave Blaney won the pole with a speed of 129.437 mph giving him his second career pole (last pole at North Carolina Speedway in February 2003) ^[2] and giving Toyota their first ever NEXTEL Cup pole position.^[3]

Shortly after the conclusion of qualifying the #83 Red Bull Toyota of Brian Vickers was found to be too low in post-qualifying inspection. Due to this his time was disallowed and he was dropped from the field. Chad Chaffin, driver of the #49 car, took his place in the starting lineup.^[4]

Others who failed to qualify: Michael Waltrip (#55), A. J. Allmendinger (#84), Kenny Wallace (#78), Scott Riggs (#10), Dale Jarrett (#44)

Jimmie Johnson led Happy Hour with a speed of 127.062 mph, while Martin Truex Jr. ran the most laps, 58. Top 5 times were as follows:

Pole sitter Dave Blaney led the first 30 laps, the most laps he had led in a race since Atlanta in March 2001. However, he lost the lead to former New Hampshire winner Jeff Gordon. After a cycle of green-flag pit stops, Dale Earnhardt Jr. assumed the top spot and led the most laps at 64. Many pit problems arose for some teams, such as speeding penalties, or running over a hose in Ryan Newman's case, or having the jack drop off the racecar, as was witnessed by the 99 crew of Carl Edwards. However, the most significant pitstop of the day was the last one. Denny Hamlin's crew chief Mike Ford took a gamble, putting on two tires, thus giving his driver the lead. Hamlin managed to hold off a furious charge from Jeff Gordon to end his 32-race winless streak and put his team back in victory lane.
