TheInfoList



OR:

Hot rods are typically American cars that might be old, classic, or modern and that have been rebuilt or modified with large engines optimised for speed and acceleration. One definition is: "a car that's been stripped down, souped up and made to go much faster." However, there is no definition of the term that is universally accepted and the term is attached to a wide range of vehicles. Most often they are individually designed and constructed using components from many makes of old or new cars, and are most prevalent in the United States and Canada. Many are intended for exhibition rather than for racing or everyday driving. The origin of the term "hot rod" is unclear. For example, some say that the term "hot" refers to the vehicle's being stolen. Other origin stories include replacing the engine's

or "rod" with a higher performance version. According to the Hot Rod Industry Alliance (HRIA) the term changes in meaning over the years, but "hot rodding has less to do with the vehicle and more to do with an attitude and lifestyle." For example, hot rods were favorites for greasers. The term has broadened to apply to other items that are modified for a particular purpose, such as "hot-rodded

Etymology

There are various theories about the origin of the term "hot rod". The common theme is that "hot" related to "hotting up" a car, which means modifying it for greater performance. One theory is that "rod" means roadster, a lightweight 2-door car which was often used as the basis for early hot rods. Another theory is that "rod" refers to
camshaft A camshaft is a shaft that contains a row of pointed cams, in order to convert rotational motion to reciprocating motion. Camshafts are used in piston engines (to operate the intake and exhaust valves), mechanically controlled ignition systems ...
, a part of the engine which was often upgraded in order to increase power output. In the early days, a car modified for increased performance was called a "gow job". This term morphed into the hot rod in the early to middle 1950s. The term "hot rod" has had various uses in relation to performance cars. For example, the Ontario Ministry of the Environment in its vehicle emissions regulations refers to a hot rod as any motorized vehicle that has a replacement engine differing from the factory original.


History

, many small military airports throughout the country were either abandoned or rarely used, allowing hot rodders across the country to race on marked courses. Originally, drag racing had tracks as long as or more, and included up to four lanes of racing simultaneously. As some hot rodders also raced on the street, a need arose for an organization to promote safety, and to provide venues for safe racing. The National Hot Rod Association was founded in 1951, to take drag racing off the streets and into controlled environments. In the '50s and '60s, the Ford flathead V8 was supplanted by the Chrysler FirePower engine (known as the "early hemi"). Many hot rods would upgrade the brakes from mechanical to hydraulic ("juice") and headlights from bulb to sealed-beam.Shelton, Chris. "Then, Now, and Forever" in ''Hot Rod'', March 2017, pp.18 and 20. A typical mid-1950s to early 1960s custom Deuce was fenderless and steeply chopped, powered by a Ford or Mercury flathead,Shelton, p.20. with an Edelbrock intake manifold, Harman and Collins magneto, and Halibrand quick-change differential. Front suspension hairpins were adapted from sprint cars, such as the Kurtis Krafts. As hot rodding became more popular, magazines and associations catering to hot rodders were started, such as the magazine ''Hot Rod'', founded in 1948.


1960 to present

As automobiles offered by the major automakers began increasing performance, the lure of hot rods began to wane. With the advent of the

caused car manufacturers to focus on fuel efficiency over performance, which led to a resurgence of interest in hot rodding. As the focus shifted away from racing, the modified cars became known as "street rods". The

(NSRA) was formed and began hosting events. By the 1970s, the small-block Chevy V8 was the most common choice of engine for hot rods. Another popular engine choice is the Ford Windsor engine. During the 1980s, many car manufacturers were reducing the displacements of their engines, thus making it harder for hot rod builders to obtain large displacement engines. Instead, engine builders had to modify the smaller engines (such as using non-standard

s) to obtain larger displacement. While current production V8s tended to be the most frequent candidates, this also applied to others. In the mid-1980s, as stock engine sizes diminished, rodders discovered the aluminum-block Buick or Oldsmobile V8 could be modified for substantially greater displacement, with mainly wrecking yard parts. This trend was not limited to American cars; Volkswagen enthusiasts similarly stretched stock 1600cc engines to over two liters.


In modern culture

There is still a vibrant hot rod culture worldwide, especially in Canada, the United States, the United Kingdom, Australia and Sweden. The hot rod community has now been subdivided into two main groups: street rodders and hot rodders.


Lifestyle

There is a contemporary movement of traditional hot rod builders, car clubs and artists who have returned to the roots of hot rodding as a lifestyle. This includes a new breed of traditional hot rod builders, artists, and styles, as well as classic style car clubs. Events like GreaseOrama feature traditional hot rods and the greaser lifestyle. Magazines like '' Ol' Skool Rodz'', '' Gears and Gals'', and '' Rat-Rods and Rust Queens'' cover events and people.

Hot rod music would prove to be the second phase in a progression known as the California Sound, which would mature into more complex topics as the decade passed. Hot rods were used as the theme of Lightning Rod, a Rocky Mountain Construction roller coaster at Dollywood.
