For the 2015 NASCAR Cup Series, power output of the competing cars ranged from 750 to 800 hp (560 to 600 kW). ==History== ===Early years=== In the 1920s, moonshine runners during the Prohibition era would often have to outrun the authorities.
They would challenge one another and eventually progressed to organized events in the early 1930s.
saw this problem, he set up a meeting at the Streamline Hotel in order to form an organization that would unify the rules. When NASCAR was first formed by France in 1948 to regulate stock car racing in the U.S, there was a requirement that any car entered be made entirely of parts available to the general public through automobile dealers.
Until the advent of the Trans-Am Series in 1967, NASCAR homologation cars were the closest thing that the public could buy that was actually very similar to the cars that were winning national races. The 1949 Oldsmobile Rocket V-8 with a displacement of is widely recognized as the first postwar modern overhead valve (OHV) engine to become available to the public.
The Oldsmobile was an immediate success in 1949 and 1950, and all the automobile manufacturers could not help noticing the higher sales of the Oldsmobile 88 to the buying public.

However, the end of the Korean War in 1953 started an economic boom, and then car buyers immediately began demanding more powerful engines. Also in 1953, NASCAR recommended that the drivers add roll bars, but did not require them. In 1955, Chrysler produced the C-300 with its Chrysler FirePower engine OHV engine, which easily won in 1955 and 1956. In 1957, several notable events happened.

Car manufacturers wanted to appear compliant with the ban, but they also wanted to win. The NASCAR tracks at the time were mainly dirt tracks with modest barriers, and during the 1957 season a Mercury Monterey crashed into the crowd.
Also 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.
General Motors' headquarters had genuinely tried to adhere to the 1957 ban, but their Chevrolet division had also constantly tried to work around it, because the other manufacturers had openly circumvented the ban.
This nose was almost a carbon copy of the nose on the 1962 Ford Mustang I prototype.
For the 1963 season NASCAR engines were restricted to using a maximum displacement of 7.0 liters (427 cu.in.) and using only two valves per cylinder. Also, even with heavy duty special editions sold to the public for homologation purposes, the race car rules were further modified, primarily in the interest of safety.
This is because race drivers and their cars during this era were subjected to forces unheard of in street use, and require a far higher level of protection than is normally afforded by truly "stock" automobile bodies. In 1963 Ford sold enough of their aerodynamic "sport-roof" edition Galaxies to the public so it would qualify as stock, and with the heavy-duty FE block bored and stroked to the new limit of 427, the top five finishers were all Fords.
In 1963 GM gave in and openly abandoned compliance, and Chevrolet was allowed to produce the ZO6 427, but it did not immediately enjoy success. Then, in 1964 the new Chrysler 426 Hemi engine so dominated the series in a Plymouth Belvedere "Sport Fury", the homologation rules were changed so that 1,000 of any engine and car had to be sold to the public to qualify as a stock part, instead of just 500.
Starting in 1963 up till this point, Ford had won six straight Manufacturer Championships, and by the end of the 1969 season Ford would make it seven in a row.

This made the 426 Hemi unavailable for the 1965 season. In 1965 Ford adapted two single-overhead-cams to their FE 427 V8 to allow it to run at a higher RPM (called the Ford 427 Cammer).
But even without the cammer, the Ford FE 427 won in 1965. In 1966 Chrysler sold enough of the 426 Hemis to make it available again, and they put it in their new Dodge Charger which had a low-drag rear window that was radically sloped.

It was called a "fast-back", and because of this David Pearson was the series champion that year with Richard Petty dominating 1967, winning 27 of 48 races (including 10 in a row) in the boxier Plymouth Belvedere. The 1969 season featured the Torino Cobra or Torino "Talladega" which had enough aerodynamic body improvements that it gave it a higher speed than the 1968 Torino, with no other changes.

The Cobra, featuring extended nose and reshaped rockers, was renamed Talladega part way through the 1969 season when the Boss 429 replaced the 427.

dealers had to be built for sale to the public to qualify, hoping to delay the use of aero-bodies until tires could improve. For the 1970 season Dodge raced the 1969 model Daytona, but Plymouth managed to build over 1,920 Plymouth Superbirds, which were similarly equipped to the Daytona.
As a result, the 1970 Homologation rules were changed so that one car for every two U.S.

NASCAR responded in a way that they hoped would make the cars safer and more equal, so the race series would be more a test of the drivers, rather than a test of car technology. The era drew to a conclusion in the 1970s.
Through the balance of the 1970s until 1992, the factory stock sheetmetal over a racing frame meant the cars looked very much like their street version counterparts.
NASCAR restricted all "aero-cars" including the Ford Talladega, Mercury Spoiler II, Charger 500, Dodge Daytona and Plymouth Superbird to a maximum engine displacement of for 1971.
1972 brought so many rule changes, it has prompted many to consider this year as the start of the modern era of NASCAR racing.
In 1972, SCCA started its first showroom stock racing series, with a price ceiling on the cars of $3,000.
The sudden infusion of noticeably larger amounts of money changed the entire nature of the sport. The 1973 oil crisis meant that large displacement special edition homologation cars of all makes were suddenly sitting unsold.
Through the balance of the 1970s until 1992, the factory stock sheetmetal over a racing frame meant the cars looked very much like their street version counterparts.
It can be said that 1993, with the addition of ground effect wrap-around type spoilers marked the beginning non-stock sheetmetal and from that point forward, stock cars were quickly allowed to differ greatly from anything available to the public.
In October 2007 American race car driver Russ Wicks set a speed record for stock cars in a 2007-season Dodge Charger built to NASCAR specifications by achieving a maximum speed of at Bonneville Speedway.
NASCAR and the auto manufacturers have become aware of this, and for 2013 each brand (Chevrolet, Dodge, Ford, and Toyota) have redesigned their racing sheetmetal to more resemble the street models of their cars. == Types of cars == A stock car, in the original sense of the term, is an automobile that has not been modified from its original factory configuration.
For the 2015 NASCAR Cup Series, power output of the competing cars ranged from 750 to 800 hp (560 to 600 kW). ==History== ===Early years=== In the 1920s, moonshine runners during the Prohibition era would often have to outrun the authorities.
