When I was at Laguna Seca I came across two cars that had been modified by the well known character, Smokey Yunick.
Smokey was known in the U.S. for his engine building skills, designer, crew chief, team owner etc and always appeared with a cigar or pipe and wearing a worn out cowboy hat. He was not a fan of all the NASCAR rules and his bending of these rules is legendary !
Smokey was at his best during the 1950s on into the 1970s.
