Danica Patrick is making her first series start since July at Daytona. Ambrose is coming off a Cup victory Monday at Watkins Glen. Edwards also is racing, former F1 champion Jacques Villeneuve will pilot the No. 22 Penske Racing Dodge that Busch won in at Watkins Glen, and Scott Speed will drive Kevin Harvick Inc.'s No. 33 Chevrolet.
