The transition to purpose-built racecars began in the early 1960s and occurred gradually over that decade. Changes made to the sport by the late 1960s brought an end to the "strictly stock" vehicles of the 1950s.
Background
Through the 1960s and 1970s the NASCAR Grand National Series began focusing on bigger, faster, and longer tracks. Like other short tracks in NASCAR at the time, crowd capacity and purses were small compared to the larger tracks. Over time, Enoch Staley and Jack Combs attempted to keep the facility modern and on pace with the growth of the sport. The West Grandstand was rebuilt with chair-type seats rather than the old bare concrete slabs. New larger restroom facilities were built, and the South Grandstand was expanded. A garage facility was also built within the track, which at the time was rare for short-track venues. But the main focus was on keeping ticket prices affordable. Food and beverage prices were kept low, and event parking and camping were always free. As long as profits covered maintenance costs, Staley was satisfied with the income of the track.
In the Gwyn Staley 160 of 1960, Junior Johnson beat 21 other drivers for the pole position with a lap speed of 83.860 mph. Glen Wood overtook Johnson to lead the first lap, but Johnson had the race under control and led the next 145 laps. Lee Petty moved up from the eighth starting position to challenge Johnson late in the race. With 14 laps remaining, Johnson and Petty made contact. Johnson's car was sent spinning into the guardrail. Petty lead the final 14 laps to win his third straight race at North Wilkesboro. The crowd of 9,200 pelted Petty with bottles, rocks, and debris after his win; he had done their local hero wrong. When Petty took the microphone in Victory Lane to explain his side of the story, the crowd began jeering. Rex White finished second, and Wood placed third. Ned Jarrett finished fourth under the alias John Lentz.
The length of the fall race in 1960 was increased from its usual 160 laps / 100 miles to 320 laps / 200 miles, this it became known as the Wilkes 320. Speeds increased immensely from the previous record, 1.83 seconds quicker than any previous qualifying lap (86.806 to 93.399 mph). Rex White posted the fastest qualifying lap and dethroned Lee Petty from his three-race winning streak at North Wilkesboro. Junior Johnson finished about half a lap behind White in second place.
In the 1961 running of the Gwyn Staley 400, Junior Johnson recorded another pole, this time by 0.57 seconds better than the previous track record, with his qualifying time of 23.52 (95.660 mph). Johnson led all of the 62 laps he ran before transmission problems forced him out of the race. Fred Lorenzen led the next 61 laps until engine problems took him out of the running. And Curtis Turner led 56 laps before experiencing problems as well. 1960 Grand National Champion Rex White, who started on the outside pole, led the remaining 221 laps and won the race. Tommy Irwin started the race in sixth position and finished the Gwyn Staley 400 two laps behind White. Richard Petty followed in third place. Fireball Roberts, in a Pontiac owned by Smokey Yunick, finished fourth (ten laps down), and Johnny Allen, who crashed out of the race on his 387th lap, still finished in fifth place. Only 12 of the 25 cars that entered the race were running at the finish of the first 400-lap edition of the Gwyn Staley race.
In the 1963 Wilkes 400, Fred Lorenzen captured his third straight pole at the track by breaking his own record with a lap time of 23.30 seconds / 96.566 mph. Richard Petty entered the race in an attempt to become the first driver to win four consecutive races at North Wilkesboro. But he experienced engine problems and lasted only 45 laps into the race. Lorenzen led 58 laps, but came up short of victory, six seconds behind winner Marvin Panch. Panch did not start the 1963 season until halfway through because he had nearly lost his life in a crash while testing a Maserati at Daytona that February. Panch, in a Wood Brothers car, started third and led 131 laps in the race. Holman-Moody took the next three spots in the final rundown, with Lorenzen second, Nelson Stacy third, and Fireball Roberts fourth. Stacy started fourth and led 56 laps, while Roberts started from the outside pole and led the most laps with 155.
The track was repaved just prior to the Gwyn Staley 400 in 1964, and the resulting lack of traction wreaked havoc. Fireball Roberts, Buck Baker, Buddy Arrington, and G.C. Spencer all crashed through the wooden guardrail in the first and second turns in Saturday's practice and qualifying. Roberts was unable to start the race because his Ford had been so heavily damaged. Fred Lorenzen won the pole and led 368 laps on the way to the win.
Race report
During this 400-lap event, the only drivers to clinch the lead were Fred Lorenzen, Junior Johnson, and Cale Yarborough. There were 35 drivers who qualified for this race; Buddy Arrington would be credited as the last-place due to being involved in an engine failure-induced accident with three other drivers on his thirteenth lap. All of the drivers on the racing grid were born in the United States of America. Most of the automobiles present at this race belong to the Ford manufacturer.[2]
Fifteen thousand fans would see an event that would last for two hours and forty-eight minutes. Fred Lorenzen would qualify for the pole position by virtue of driving up to 101.58 miles per hour or 163.48 kilometres per hour during his solo qualifying session. Only two of the top-ten finishers would drive a Dodge vehicle while Chevrolet stock cars would finish anywhere between the middle of the pack to near the end of the pack.[2] Junior Johnson defeated Cale Yarborough by two laps in order to clinch his final victory ever in the NASCAR Cup Series.[2]
Frank Weathers would retire from driving in the top-level NASCAR series after this event.[3]John Ervin, Herb Nab and Dale Inman where the three most notable crew chiefs to participate in this event.[4]
