One popular idea was to use 231–275 cu in (3.8–4.5 L) six-cylinder engines; instead of Cup Series' 358 cu in (5.9 L) V-8s. [5] [6] [7] In 1989, NASCAR changed rules requiring cars to use current body styles, similar to the Cup cars. However, the cars still used V6 engines. The cars gradually became similar to Cup cars.
