Stock car racing is a form of automobile racing run on oval tracks and road courses measuring approximately 0.25 to 2.66 miles. It means originally used production-model cars, hence the name "stock car", but is now run using cars specifically built for racing. It originated in the southern United States; its largest governing body is NASCAR. Its NASCAR Cup Series is the premier top-level series of professional stock car racing. Australia, Canada, New Zealand, Mexico, Brazil, Argentina, and the United Kingdom also have forms of stock car racing. Top-level races typically range between 200 and 600 miles in length.
Pontiac, or formally the Pontiac Motor Division of General Motors, was an American automobile brand owned, manufactured, and commercialized by General Motors. It was originally introduced as a companion make for GM's more expensive line of Oakland automobiles. Pontiac quickly overtook Oakland in popularity and supplanted its parent entirely by 1933, in turn establishing its position as one of the GM's dominant divisions.
The NASCAR Xfinity Series (NXS) is a stock car racing series organized by NASCAR. It is promoted as NASCAR's second-tier circuit to the organization's top level Cup Series. NXS events are frequently held as a support race on the day prior to a Cup Series event scheduled for that weekend.
The Buick Skylark is a passenger car formerly produced by Buick. The model was made in six production runs, during 46 years, over which the car's design varied dramatically due to changing technology, tastes, and new standards implemented over the years.

The Pontiac Bonneville is a model line of full-size or mid-size front-engine rear drive cars manufactured and marketed by Pontiac from 1957 until 2005, with a hiatus for model years 1982-1986.
A restrictor plate or air restrictor is a device installed at the intake of an engine to limit its power. This kind of system is occasionally used in road vehicles for insurance purposes, but mainly in automobile racing, to limit top speed to provide equal level of competition, and to lower costs; insurance purposes have also factored in for motorsports.
The Iron Duke engine is a 151 cu in (2.5 L) straight-4 piston engine built by the Pontiac Motor Division of General Motors from 1977 until 1993. Originally developed as Pontiac's new economy car engine, it was used in a wide variety of vehicles across GM's lineup in the 1980s as well as supplied to American Motors Corporation (AMC). The engine was engineered for fuel efficiency, smooth operation, and long life, not for performance. Total Duke engine production is estimated to be between 3.8 and 4.2 million units.
The General Motors 60° V6 engine family is a series of 60° V6 engines produced for both longitudinal and transverse applications. All of these engines are 12-valve cam-in-block or overhead valve engines, except for the LQ1 which uses 24 valves driven by dual overhead cams. These engines vary in displacement between 2.5 and 3.4 litres and have a cast-iron block and either cast-iron or aluminum heads. Production of these engines began in 1980 and ended in 2005 in the U.S., with production continued in China until 2010. This engine family was the basis for the GM High Value engine family.

Introduced for the 1970 model year, the model line was produced across six generations through the 2008 model year, with a hiatus from 1989 to 1994. The Monte Carlo was a closely aligned variant of the Pontiac Grand Prix through its entire production.
The General Motors G platform was an automobile platform designation used for mid-sized rear-wheel drive cars. It made its first appearance from the 1969 to 1972 model years, adapted from GM's A-body, and reappeared from 1982 to 1988.

The GM A platform was a rear wheel drive automobile platform designation used by General Motors from 1925 until 1959, and again from 1964 to 1981. In 1982, GM introduced a new front wheel drive A platform, and existing intermediate rear wheel drive products were redesignated as G-bodies.

The 1981 NASCAR Winston Cup Series was the thirty-third season of professional stock car racing in the United States and the 10th modern-era Cup Season. It was the first year of the Gen 3 car. Because of the energy crisis, manufacturers were downsizing their cars to be more fuel-efficient, which NASCAR reflected by mandating a 110-inch wheelbase that still exists today. The season began at Riverside International Raceway with the first Winston Western 500 on January 11, 1981 and ended with the same event on November 22. Darrell Waltrip won his first championship with point margin of fifty-three points over Bobby Allison. Ron Bouchard was named Rookie of the Year.

The generation has been described as the generation that removed all "stock" aspects from stock car racing and is as aerodynamically sensitive as a Le Mans Prototype.
The Generation 2 in NASCAR refers to the cars used between 1967 and 1980. The second generation of stock cars featured stock body with a modified frame, and modified chassis became part of the sport with entities such as Holman-Moody, Banjo Matthews, and Hutchenson-Pagan building chassis for teams.
NASCAR, the highest governing body and top level division for stock car racing in the United States, has used a range of different types of engine configurations and displacements since its inaugural season in 1949. The engines are currently used in the Cup Series, Xfinity Series, Camping World Truck Series, and the Whelen Modified Tour.
