All forms of racing require specialized equipment, but none is so specialized as the unlimited drag racing machine. This dragster was built by Don Garlits. The engine was built by Keith Black with port injection, a Roots-type blower and a displacement of 501 cubic inches. Burning a mixture of 90 percent nitromethane and 10 percent benzine, it produces 2,000 hp for brief periods. In actual operation the engine runs for no more than 20 to 30 seconds at a time. This includes the “burn out” (when when traction compound is poured on the tires after which the driver deliberately spins the rear wheels to ignite the compound, which softens the tires for better traction), warm up, and actual run down the quarter-mile course.
This dragster was driven by Don “Big Daddy” Garlits during the 1974 season and won the American Hot Rod Association (AHRA) meets in Louisiana, Texas, Kansas, Arizona and Ohio. It was the AHRA champion in 1974 and finished the season by winning the National Hot Rod Association (NHRA) Super Nationals at Ontario, California. Top speed for both AHRA and NHRA was 247.25 mph with an elapsed time for the standing start quarter-mile of 5.78 seconds.
