races with mechanical problems (two of the 21 races he did not finish that season), before earning his third career win at Beltsville Speedway. For 1967, he teamed once again with Stelter for the majority of the year but it was with Petty Enterprises in the No. 42 Plymouth that he had most of his success. Lund finished fourth in the Daytona 500 despite running out of fuel with a lap to go. Lund finished fifth in the World 600 for Petty Enterprises. He struggled in Stelter's Fords despite a promising run in Fonda, New York, where he qualified second and led some laps before an axle broke. Lund and Stelter parted at season's end. For 1968, he teamed with Bud Moore and his Mercurys, finishing fifth in the Firecracker 400 and fourth in Rockingham during his shortened Grand National season. In 1968, Lund appeared as one of the race drivers in the racing scene of the MGM movie Speedway which starred Elvis Presley and Nancy Sinatra. In 1969, Lund entered one Grand National race, guesting for Bill France Sr. in the inaugural Talladega 500. The race is known for a drivers' boycott over tire safety protests. Lund drove into the lead but his clutch failed and he was classified ninth. Success in Grand American series From 1968 through 1971, Lund earned his greatest racing successes in the new NASCAR Grand American Series, winning 41 of the 109 Grand American races from 1968 through 1971. The series was designed for pony cars like Ford Mustangs, Chevrolet Camaros and Mercury Cougars. Lund drove a Cougar for the Bud Moore team in 1968, winning the inaugural season championship. Lund would win back-to-back Grand American championships in 1970 and 1971, driving a Camaro for the Ronnie Hopkins team. Lund "won" two Grand National events in 1971 – both times driving his Grand American pony car. As the number of entrants for some of the smaller Grand National races were low (only 14 cars entered the 1971 Space City 300), NASCAR decided to allow Grand American cars to fill out the remaining spots at six Grand National races later in the year. Three of these Grand National races were won by drivers in Grand American cars; Lund drove the Camaro to victory in the Buddy Shuman 276 and the Wilkes 400, while Bobby Allison drove a Mustang to victory in the Myers Brothers 250.
