Jim Dittemore was a solid performer in the L&M Continental 5000 Championship driving a Lola T-192 prepared and entered by Kas Kastner and John Brophy. Starting with his second- place finish in the L&M Grand Prix at Riverside, Dittemore stayed well up in the standings. He finished fourth in the race at Laguna Seca, third at Edmonton, Alberta, and took a pair of ninth place finishes at Seattle and Elkhart Lake, Wis. He also went back to Seattle to run the 1971 United States Auto Club road racing event and won it, worth the title, “1971 USAC Road Racing Champion.” Dittemore raced for Kas Kastner for years when Kastner was head of the Triumph Competition Department. He was Southern Pacific divisional champion in class D Production in 1967 and drove a Kastner TR-6 to SCCA national championship victories at San Jacinto and Seattle, and a Lola Formula Ford to victories at Riverside and Laguna Seca.
