“He was a helping hand, the guy I could turn to for guidance,” said a drag racer speaking of Keith Black, whose racing engines—aluminum blocks fashioned after the Chrysler 392 Hemi—continue to dominate drag racing. Keith Black Racing Engines opened in 1959, and KB blocks held every national record in Top Fuel between 1975 and 1984; his high-performance drag racing engines also showed up in tractor pulling applications. In the mid-1940s, he segued to boat racing, setting a world record at Salton Sea on his second time out. In the mid-1960s Chrysler contracted him to develop a marine racing program.
