In 1990, Grice and his old Roadways touring car team led by team boss and chief mechanic Les Small, developed a left-hand-drive Holden VN Commodore powered by a 358 cubic inch Chevrolet V8 engine to run in the Australian NASCAR series, with Grice taking several wins at both the Thunderdome and the 1/2 mile Speedway Super Bowl at the Adelaide International Raceway. Grice, Small and Bob Jane also formed a plan to take the Commodore to America to run in the Winston Cup], though ultimately the plans were shelved.
