On August 16, 1970, while big-blocks still reigned supreme, NASCAR mandated the first use of restrictor plates with maximum venturi openings of 1.25 inches. Following fatal crashes of Adam Petty and Kenny Irwin Jr. at the New Hampshire International Speedway during the May Busch Series and July Winston Cup Series races, respectively, NASCAR adopted a one-inch (2.54cm) restrictor plate to slow the cars headed towards the tight turns as part of a series of reforms to alleviate stuck throttle problems which were alleged to have caused both fatal crashes.

Buddy Baker nosed out Richard Petty in a photo finish to win the race, which was marred by the death Lund who was involved in a multi-car crash on the seventh lap. In restrictor plate racing the packs have brought about an often-enormous increase in positional passing; at Talladega Superspeedway the Sprint Cup cars have broken 40 official lead changes sixteen times from 1988 onward, including both 2010 Sprint Cup races at Talladega, which had 87 official lead changes in the regulation 188 laps. For the 1963 season NASCAR engines were restricted to using a maximum displacement of 427cuin (7.0L), and using only two valves per cylinder. For pistons ECR uses MAHLE. Jeff Burton led all 300 laps in the ensuing race, despite a 23-car two-abreast battle in the first ten laps, a dramatic charge past 22 cars in 100 laps by John Andretti (who finished seventh), and two charges by Bobby Labonte in the final 50 laps where he took the lead but Burton beat him back to the stripe. It was the most competitive title chase in NASCAR history, with Isaac only winning the championship by a mere 51 points. Rather, aerodynamic air intake reduction through the use of a 390 cfm carburetor, and eventually a tapered carburetor spacer was implemented for those races.

The King of the Jungle features a roaring, 5,000 horsepower, twin-turbo, 526 cid Hemi engine from Brad Anderson Enterprises. As a safety measure to reduce speeds at the two high-banked superspeedways (Daytona and Talladega), restrictor plates are used. Displacements included 332, 352, 360, 390, 406, 410, 427, and 428.

I started 955 Automotive in 2004, Jason says. The only body style available was the two-door hardtop, although buyers could dress it up with a vinyl roof, and several engines were available. The reduction in throttle response, however, has never been shown to have impeded the ability to pass; the criticism was shot down in the first "modern" plate race, the 1988 Daytona 500, as the lead changed 25 times officially and saw several bursts where the lead changed several times a lap and also several bursts of sustained side-by-side racing, notably in the final 50 laps between Bobby Allison, Darrell Waltrip, Neil Bonnett, and Buddy Baker.
