General Challenger

  • High Impact Paint

    In the late 60s/early 70s, Dodge was already offering some of the hottest cars of the muscle car era- awesome machines like the Hemi Challenger and 440 Six-Pack Super Bee. Designers, however, decided to rev up the cars’ visuals to match, creating a far-out assortment of vibrant exterior paint colors. These special colors (a $15 option) generated a big buzz in the showrooms and launched an industry trend. The color palettes used by all the automakers were opened up, giving paint designers...
  • History of the Dodge Logo

    Dodge was founded in 1900 by Horace and John Dodge (The Dodge Brothers). It was initially known as the Dodge Brothers Company and used to sell bicycles, but then within two years it became a major supplier of axles, engines, and transmissions to the automobile industry. The company started by producing chassis and engines for the Ford Motor Company and Olds Motor Vehicle Company. However, with the stress and demands of the booming automobile industry, the brothers decided to tinker with the...
  • The Origin of Scat Pack

    The Dodge Scat Pack was originally introduced in 1968 with the Charger R/T, Coronet R/T, Dart GTS, and Super Bee. In order for a car to enter the Scat Pack it had to be capable of running the quarter mile in the 14s (14.99 or faster). Mainly a marketing term, Scat Pack cars got twin bumblebee stripes and special decals. It became legendary in the enthusiast community and symbolized one of the most feared groups of street machines every to rumble from stoplight to stoplight. In the early...
  • Paddle shifters

    Paddle shifters, once exclusive to race cars and exotic sports cars, like the Ferrari F430, are now becoming commonplace on performance cars with automatic transmissions. This is because manual transmissions are going away faster than the landline telephone. Critics of automatics say that they take the passion and command out of driving. Paddle shifters, however, bring some of that joy and control back by allowing drivers to manually shift an automatic transmission with steering-wheel or...
  1. Mopar Engine Colors

    Automobile engines are usually painted bright colors, like red, orange or blue. This just isn’t for appearance. There is a practical purpose. Bright colors enable leaks to be spotted easily. Here is a list of engine colors (and paint codes) used by Mopar, from 1962 to 1971. Race Hemi Orange- Mopar P4120751 1962-1964 Max Wedge engines (413 and 426 Cross Ram) 1964-1965 426 Race Hemis Street Hemi Orange- Mopar P4349216 1966-1971 426 Street Hemis 1969-1971 High performance 383 and 440...
  2. Mufflers

    Since the beginning of hot rodding, enthusiasts have tinkered with their car’s exhaust system, particularly the mufflers, to get the “right sound.” A muffler’s job sounds easy enough- reduce exhaust volume to tolerable levels while allowing the sweet sounds of your ride to waft through the air. But this becomes a monumental task as horsepower increases. Engines build horsepower by pushing spent exhaust out of the tailpipe as fast as possible. As pistons furiously churn, exhaust velocity...
  3. Nitrous Oxide

    Juice. Squeeze. Laughing gas. Nitrous oxide has many aliases. It can inject a healthy dose of horsepower into an engine, via direct port, carburetor/throttle body plate, air intake tube or, air cleaner injection, to give a race car the winning edge at the track. In racing, nitrous oxide (often referred to as just "nitrous") allows an engine to burn more fuel by providing more oxygen than air alone, resulting in a more powerful combustion. The gas is not flammable at a low...

  5. Pro Stock Record Holders

    Pro Stock quarter mile drag racing times have dramatically decreased over the decades, since the class was established in 1970. This has been the result of tremendous advances in technology. To determine who is the fastest competitor, forty-nine years ago, NHRA instituted the Mello Yello Drag Racing Series. The champion is determined by a point system where points are given according to finishing placement and qualifying effort. The season is divided into two segments. After the first 18...
  6. Ralph Gilles- A Real Mopar Guy

    Mopar enthusiasts owe the fantastic array of performance models to Ralph Gilles, Head of Design for Fiat Chrysler Automobiles. We are truly fortunate to have a cool car guy in charge. Gilles, as a boy living in Quebec, was drawing concept vehicles at the age of eight. When he was fourteen years old, his aunt sent one of his sketches to Chrysler Chairman Lee Iacocca. A reply came from K. Neil Walling, Chrysler's design chief at the time, suggesting he attend one of three design schools....

    Rear Window Louvers

    The rear window louvers that were original equipment on some 60s and 70s muscle cars were first and foremost, styling statements. They were part of an appearance package that was created to set these cars apart from lower performance plain Jane versions and were usually combined with features like stripes, spoilers and vinyl roofs. In addition, while they did not improve the aerodynamics of the vehicle, they created a dead air zone that helped traction by reducing rear lift. Some pony...
  8. Rearview/Back-up Camera

    A backup camera (also called a reversing camera or rearview camera) is a special type of video camera that is attached to the rear of a vehicle to alleviate the rear blind spot and avoid a backup collision. The area directly behind vehicles has been described as a "killing zone" due to associated accidents. Backup cameras are usually connected to the vehicle’s head unit display. The first backup camera was used in the 1956 Buick Centurion concept car, presented in January 1956, at the...
  9. Ronnie Sox- A Tribute to "Mr. Four Speed"

    Ronnie Sox is one of the greatest Mopar drag racers. Like many who eventually became professional racers, "The Boss," grew up around cars, raised in the shadow of his family’s Sinclair service station. As soon as he was old enough to drive, Sox began competing in drag races, sponsored by the Police Club of Burlington, NC, at a local airport. In the early days, Sox didn’t even own a car and used his father’s 1949 Olds. From these humble beginnings, Sox would go on to become what many...
  10. Safety Regulations/Equipment for Racing

    If you plan to enter your vehicle in any competition sanctioned by the NHRA, your Challenger is going to have to pass a series of pre-race inspections for the required safety equipment. These requirements get more stringent as the expected horsepower and speeds increase.The SFI Foundation sets the standard for quality assurance in the vast majority of aftermarket and performance products. Basic Safety The basic safety stuff for the street legal classes is pretty simple. You’ve got to have...

    Seat Belt Technology

    A seat belt is a vehicle safety device designed to secure the driver or a passenger of a vehicle against harmful movement that may result during a collision or a sudden stop. A seat belt reduces the likelihood of death or serious injury in a traffic collision by reducing the force of secondary impacts with interior strike hazards, by keeping occupants positioned correctly for maximum effectiveness of the airbag (if equipped) and by preventing occupants being ejected from the vehicle in a...
  12. Shock Absorbers

    An automobile shock absorber is basically a hydraulic piston that absorbs and dissipates vibration using spring-loaded check valves and orifices to control the flow of oil. The first production hydraulic dampers, to act on the main leaf spring movement, were probably those based on an original 1908 concept by Maurice Houdaille. One design consideration, when designing or choosing a shock absorber, is where that energy will go. In most shock absorbers, energy is converted to heat inside the...
  13. Slicks & Drag Radials

    Drag radial street-legal tires had their origin in racing. Originally, race cars used “racing slicks”- a type of tire with a smooth tread. The first production "slicks” were developed by M&H Tires in the early 1950s for use in contact patch to the track and maximized traction for any given tire dimension. Slicks were also used on road and oval track racing where steering and braking require maximum traction from each wheel. Slicks, however, are not suitable for use on street cars which...
  14. Superchargers vs. Turbochargers

    When designing an engine to pull in more than atmospheric pressure, engineers often turn to forced induction. It’s one of the fastest ways to add significant power to almost any engine, and there are two prevalent ways it can be done: supercharging and turbocharging. But, which is better? Both are different in terms of how they work, performance and cost. Both operate on the principle that the more air you can get into your engine, the more power your car will make. Supercharging is old...
  15. The Meaning of "Mopar"

    Short for the Chrysler Motor Parts Corporation, Mopar made its first appearance in the late 1920s and became its own brand in 1937. The name Mopar was created by a committee to market cans of "Chrysler Motor Parts" antifreeze. From there, the Mopar catalog expanded to include waxes, cleaners, filters, engine parts and more. Now, in its 81st year, Mopar encompasses the full line of Fiat Chrysler Automobiles parts, accessories, and customer service, including Fiat and Alfa Romeo brands...
