By the 1975 NASCAR Winston Cup season, all cars were equipped with the same-size engines, eliminating the need for the restrictor plates that were required for large-engine cars, and creating a more level playing field. To get the results from the 30 races of the 1975 NASCAR Winston Cup season, see the chart below.
 Buddy Baker put his #15 Ford on the pole for the May 4, 1975 Winston 500 at Talladega. See more pictures of NASCAR. |
