#400 for Chevy:

#48-Jimmie Johnson, driver of the Lowe’s Monte Carlo, won the New England 300 at New Hampshire International Speedway and gave Chevrolet its 400th victory of the modern era (1972-present) in NASCAR Winston Cup racing. Chevrolet’s 400th victory of the modern era began with Bobby Allison’s win at Atlanta International Raceway [now Atlanta Motor Speedway] on March 26, 1972. His car owner at that time was Richard Howard, and his team manager that season was Junior Johnson. Allison’s victory at Atlanta was the first for a Chevrolet on a superspeedway since Johnson won at Charlotte in October 1963.(GM Racing PR)(7-21-2003)
