About the only things on these cars that resembled showroom models were the bumpers, nose, and tail. Steel bodies were replaced by fiberglass to reduce weight. Wind tunnels became a staple as teams worked to gain aerodynamic advantages. NASCAR also requires teams to use blocks, cylinders and intake manifolds made from castings of approved manufacturers. A large engine has the capacity to produce more power. On long straight tracks, NASCAR mandates the use of restrictor plates or sleeves to limit the speed of the cars. The following race at Talladega that year would be run with a smaller carburetor, however, NASCAR mandated the use of the restrictor plate at the end of the season. For the Winston Cup race, it was used just once at the 2000 Dura Lube 300. Whether they produce 750HP or 450HP, NASCAR engines are outstanding examples of technology refined over many years and today represent the peak of performance, power, and reliability. All the subsystems like coolant pumps, oil pumps, steering pumps, and alternators are designed to run at sustained high speeds and temperatures.

Dodge departed the sport after winning the 2012 championship with Brad Keselowski as very few teams had signed with the OEM for the Gen-6 era. The restrictor plate limits air into the engine, reducing horsepower and speed at these tracks from 230-240mph to 195-200mph.

Teams spend a lot of money on the engines and their construction and costs are kept secret. The side oiler was more expensive to build and added significant cost to the window sticker of any car it was installed in, which served to keep buyers away. In addition to being available in the Cobra, it was largely limited to large, full-size cars like the Ford Galaxie and the Mercury Marauder, where it provided excellent power but was countered by the additional weight and plus-size proportions of those vehicles.

A compromise of sorts was eventually reached in 1966, when the governing body decided to allow a restricted version of the 427 Cammer to run in full-size sedans as long as the driver carried enough ballast along with them to boost overall vehicle weight to 4,400 lbs (nearly 430 lbs more than comparable Dodges). The heavy support from the three parent companies meant teams to could still buy body panels and other parts directly from the manufacturers. But make no mistake. Chevrolet, Ford, and Toyota unveiled the now current generation of NASCAR machines. On 23rd May 1987, NASCAR driver Bobby Allison, racing in the Winston 500 competition, crashed on the 22nd lap at the Talladega Superspeedway. -Strictly stock frame and body.

In 1957, Chevrolet sold enough of their new fuel injected engines to the public in order to make them available for racing (and Ford began selling superchargers as an option), but Bill France immediately banned fuel injection and superchargers from NASCAR before they could race. Would love your thoughts, please comment. This extended to the bumpers, nose, and tail of the car. Small-block engines, in the 358 cubic inch range, were exempt from the plates; the first car to race with a small-block engine was Dick Brooks at the 1971 Daytona 500, where he ran a 1969 Dodge Daytona with a 305 CID engine. Cars featured no doors, bigger spoilers, and streamlined designs. These cars barely resembled their showroom counterparts. Wheelbase was reduced to 110 inches, making these cars smaller than previous generations. Any part that needs replacement is replaced before the engine is returned to the team. So F Rusty Wallace tested a car at Talladega Superspeedway without a restrictor plate in 2004, reaching a top speed of 228mph (367km/h) in the backstretch and a one-lap average of 221mph (356km/h). At Daytona and Talladega, most races are marred by at least one wreck, usually referred to as "the Big One", as cars rarely become separated. I was told that after NASCAR went to a 358 cube rule in 1974, Chevy used smaller cubic inch versions of the big block and not the SBC. This reduced the weight of the car and gave it an even greater weight-to-power ratio. The wear due to friction is additionally taken off by the special coatings on the rotating parts. The oil is pumped out as it drips from the rotating parts, allowing them to rotate in clean air, this increases the power output of the engine by as much as twenty per cent. There have been four eras that NASCAR used restrictor plates. They wanted more than one manufacturer, but they wanted all the engines to be similarly powered so that none were more dominant than the others.
