1970 Tidewater 300

Considered to be the 48th event of the 1970 season, this race was the final race of an unregulated stock car racing organization without a corporate sponsor. Economic issues and the need to increase the total amount of winnings for each qualifying participant required NASCAR to accept a major corporate sponsor to bankroll what will become multimillion-dollar purses by the end of the 20th century. Like all races done before the 1973 oil crisis, the stock cars were considered to be the same vehicles that the drivers drove to the racetrack in. Homologation rules would remain strict until approximately 1975 when the NASCAR teams would abandon the Detroit factories and set up their own race car factories in the South Carolina area.

The race was decided in a time of one hour and forty minutes. Bobby Allison was declared the race winner.^[2] There were two cautions (for ten laps) and 3,200 people attended this 300 lap (118.5 miles) race.^[2] Speeds approached 69.584 miles per hour (111.985 km/h) as the average and 78.239 miles per hour (125.913 km/h) for the pole position speed.^[2] The margin of victory was only one hundred yards^[2] (the equivalent of a football field as used by the National Football League). Other top participants were Benny Parsons (with his first career pole position), Pete Hamilton, John Sears, James Hylton, Neil Castles, Elmo Langley, J.D. McDuffie, Frank Warren, and Jabe Thomas.^[2] This was the biggest racing grid of any race on the site at Langley with 30 drivers competing at the start.^[2] However, only twenty of them managed to complete the race.^[2]

The top prize of the race was $1,635 ($13,238 when adjusted for inflation) and the prize for thirtieth place was $200 ($1,619 when adjusted for inflation).^[2] Total winnings were considered to be $10,015 ($81,090 when adjusted for inflation). Benny Parsons and Bobby Allison were constantly competing for the lead in parts of the race. Most of the vehicles that failed to finish the race were due to problems in their engine.^[2]

Roy Tyner would race his final NASCAR Cup series race here while Rodney Bruce would make his only NASCAR Grand National Series appearance.^[4]

Notable crew chiefs for this race included Junie Donlavey, Harry Hyde, Lee Gordon and Don Lawrence.^[5]

Unfortunately, it would also be the last race ever for Langley Field. Even though the race was more than 300 miles, it was not considered to be modern enough for the evolving vehicles of what would become the NASCAR Winston Cup Series the following year. Many of the "pioneer race courses" did not survive NASCAR's abbreviated schedule as the organizers believed that the older tracks were not modern enough for the faster and newer vehicles.

After years of not needing a primary sponsor, the Big Tobacco conglomerate R. J. Reynolds Tobacco Company would become the main sponsor the following season with their Winston cigarette brand. Using their once-abundant profit margin they acquired while getting America's adult smokers to use their products on a habitual basis, the new primary sponsor would help bring NASCAR into its "modern era." This would bring about the unintended consequences of non-automotive sponsors into the sport. An increasing level of media coverage outside of the American Deep South would also help to bring the sport into the modern era.

Giveaway products in later years like T-shirts, knives, and cigarette lighters were often used as merchandise items handed out by American variety stores. All the customer had to was purchase a carton of Winston cigarettes and the bonus item would be added free of charge. All other cigarette products would not allow the customer to acquire free NASCAR merchandise because only the Winston brand was considered the official tobacco product of NASCAR. Unlike the more expensive items like jackets, merchandise from the main sponsor often dealt with NASCAR in general and never with a specific driver.

Reynolds' premier cigarette brand would remain as NASCAR's top sponsor until 2004 when a telecommunications company known as Nextel Communications would take over due to declining North American tobacco sales in the 21st century. This would force the Winston Cup Series (also known as the Winston Cup Grand National Series prior to circa 1985) to change its name to the Nextel Cup Series. Computer games released from 2005 to the present day (i.e., NASCAR 2005: Chase for the Cup, NASCAR SimRacing) were allowed to use the name of NASCAR's premier racing series without having to use an ambiguous title because tobacco was no longer involved in its sponsorship. After a few years, the Nextel company would merge with another telecommunications company to form the Sprint Nextel company. This new corporate sponsor would take over primary sponsorship starting in 2008 (making it necessary to change the name of the Nextel Cup Series into the Sprint Cup Series).
