In the 1980s, it became prohibitively expensive for modified teams to tow long distances to sixty or more races per year, including Watkins Glen International and Daytona International Speedway, Bowman Gray Stadium in Winston-Salem, North Carolina, North Wilkesboro Speedway, and Martinsville Speedway, with the North Wilkesboro races part of the Cup weekend. To enable more than a few teams to contend seriously for the championship, it was decided to reformat the Modified Division's championship to a limited schedule of races not conflicting with one another. This change mirrored similar format changes to the Grand National Division starting in 1972 and the Late Model Sportsman Division (now Xfinity Series) starting in 1982. Richie Evans ran 66 NASCAR modified features (and several unsanctioned events such as the Race of Champions) in 1984, the final year of the old system.
