The series is not only developmental for drivers (including Joey Logano, Martin Truex Jr., Ricky Craven, Mike McLaughlin, Austin Dillon, Trevor Bayne, Brian Ickler, Ricky Carmichael and Ryan Truex), but for crew members (such as Greg Zipadelli and Marc Puchalski) and officials, as well.Formed as the NASCAR Busch Grand National North Series in 1987, the series originally raced primarily in the Northeastern United States, including Maine, New Hampshire, Vermont, Massachusetts, New York, New Jersey, Connecticut, and Pennsylvania.In 2002, a big crash occurred at the Glen that saw many cars spinning through the esses on lap one, along with Troy Williams actually overturning over the guardrail.The series name was changed to Busch East for the 2006 season after a race was added in Greenville-Pickens Speedway in South Carolina.Races were added in South Boston, Virginia, and Nashville, Tennessee for 2007 to continue the push South and West, as well as East-West combination races at the Iowa Speedway in Newton, IA and Elko Speedway in Elko, MN..For 2013 NASCAR made several rule changes including giving team the option of using "special" engines and a composite body to reduce the cost of competing in the K&N Series.On December 16, 2019, NASCAR announced that Camping World would take over as title sponsor of both series in the Grand National Division.When the series first started, the cars ran a V6 engine with a maximum 274 cu in (4,490 cm3) displacement and no compression limit.
