It wasn't until 2002 that Scarallo joined the
North American Trans-Am Championship. In February of that year, Scarallo was invited to drive for
K&N Air Filters in a company development car, in the 24 Hours of Daytona. The car was an Ultima GTR. After breaking many times throughout the race, the car was finally retired during the night portion of the race. In 2004, Scarallo was hired to race in the 3-Hour Endurance race of Puerto Rico with teammate Jorge Diaz, another Trans-Am competitor. After qualifying on pole and leading every lap of the race Scarallo, became the very first American to win the event. 2005 was a very competitive year with many laps led, and a fifth place championship finish. The
Trans-Am Championship went on hiatus after 2006 and Scarallo moved over to run in the
SCCA World Challenge in the GT class with a Pontiac GTO. In 2010, Scarallo made his
NASCAR debut in the
Nationwide Series when he was hired by a team to run on the
Road America and
Watkins Glen road courses helping them collect base prize money for qualifying and pulling out of the races early. Many lower budget NASCAR teams do this as a full-time revenue source, deriving the term "Start and Park". ==Career results==
