This is the Heth & Thompson car from Colorado. It was the first car to break 160 mph (June 5, 1960) and 170 mph (178.57 on August 14, 1960). The Heth & Thompson team was nearly unbeatable for three years. They eventually bought Tommy Ivo's first Buick dragster (less engine) from Don Prudhomme, put their Chrysler in it, and continued to dominate.
