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, mechanically controlled ignition systems and early electric motor speed controllers.
Top Fuel is a type of drag racing whose dragsters are the quickest accelerating racing cars in the world and the fastest sanctioned category of drag racing, with the fastest competitors reaching speeds of 341.68 miles per hour (549.9 km/h) and finishing the 1,000 foot (304.8 m) runs in 3.62 seconds.
A replacement automobile engine is an engine or a major part of one that is sold individually without any other parts required to make a functional car. These engines are produced either as aftermarket parts or as reproductions of an engine that has gone out of production.
Variable valve timing (VVT) is the process of altering the timing of a valve lift event in an internal combustion engine, and is often used to improve performance, fuel economy or emissions. It is increasingly being used in combination with variable valve lift systems. There are many ways in which this can be achieved, ranging from mechanical devices to electro-hydraulic and camless systems. Increasingly strict emissions regulations are causing many automotive manufacturers to use VVT systems.
The GM Ecotec engine, also known by its codename L850, is a family of all-aluminium inline-four engines, displacing between 1.2 and 2.5 litres. Confusingly, the Ecotec name was also applied to both the Buick V6 Engine when used in Holden Vehicles, as well as the final DOHC derivatives of the previous GM Family II engine; the architecture was substantially re-engineered for this new Ecotec application produced since 2000. This engine family replaced the GM Family II engine, the GM 122 engine, the Saab H engine, and the Quad 4 engine. It is manufactured in multiple locations, to include Spring Hill Manufacturing, in Spring Hill, Tennessee, with engine blocks and cylinder heads cast at Saginaw Metal Casting Operations in Saginaw, Michigan.
The Chevrolet small-block engine is a series of gasoline-powered V8 automobile engines, produced by the Chevrolet division of General Motors between 1954 and 2003, using the same basic engine block. Referred to as a "small-block" for its size relative to the physically much larger Chevrolet big-block engines, the small-block family spanned from 262 cu in (4.3 L) to 400 cu in (6.6 L) in displacement. Engineer Ed Cole is credited with leading the design for this engine. The engine block and cylinder heads were cast at Saginaw Metal Casting Operations in Saginaw, Michigan.
An overhead camshaft (OHC) engine is a piston engine in which the camshaft is located in the cylinder head above the combustion chamber. This contrasts with earlier overhead valve engines (OHV), where the camshaft is located below the combustion chamber in the engine block.
An overhead valve engine, abbreviated (OHV) and sometimes called a pushrod engine, is a piston engine whose valves are located in the cylinder head above the combustion chamber. This contrasts with flathead engines, where the valves were located below the combustion chamber in the engine block.
The Quad 4 is a family of straight-four engines produced by General Motors' Oldsmobile division. Several double overhead camshaft (DOHC) versions were produced between 1987 and 2002, and one single overhead camshaft (SOHC) model was built from 1992 to 1994.
The Ford flathead V8 is a V8 engine with a flat cylinder head introduced by the Ford Motor Company in 1932 and built by Ford through 1953. During the engine's first decade of production, when overhead-valve engines were used by only a small minority of makes, it was usually known simply as the Ford V‑8, and the first car model in which it was installed, the Model 18, was often called simply the "Ford V-8" after its new engine. An automotive milestone as the first affordable V8, it ranks as one of the company's most important developments. The engine was intended to be used for big passenger cars and trucks; it was installed in such until 1953, making the engine's 21-year production run for the U.S. consumer market longer than the 19-year run of the Ford Model T engine. It was also built independently by Ford licensees.. The engine was named on Ward's list of the 10 best engines of the 20th century. It was a staple of hot rodders in the 1950s, and it remains famous in the classic car hobbies even today, despite the huge variety of other popular V8s that followed.
A flathead engine, also known as a sidevalve engine or valve-in-block engine, is an internal combustion engine with its poppet valves contained within the engine block, instead of in the cylinder head, as in an overhead valve engine.
A tappet or valve lifter is a valve train component which converts rotational motion into linear motion in activating a valve. It is most commonly found in internal combustion engines, where it converts the rotational motion of the camshaft into linear motion of intake and exhaust valves, either directly or indirectly.
Edelbrock, LLC is an American manufacturer of specialty automotive and motorcycle parts. The company is headquartered in the Memphis area, with a Southern California R&D Tech Center located in Cerritos, CA. The Edelbrock Sand Cast and Permanent Mold Manufacturing foundries are located in San Jacinto, CA. Edelbrock has two facilities in North Carolina: the Edelbrock Carburetor Division in Sanford, and the Edelbrock Race Center in Mooresville.
A valvetrain is a mechanical system that controls the operation of the intake and exhaust valves in an internal combustion engine. The intake valves control the flow of air/fuel mixture into the combustion chamber, while the exhaust valves control the flow of spent exhaust gases out of the combustion chamber once combustion is completed.
Dean Moon was an American automobile designer. He grew up in Norwalk, California. Moon was around cars and racing from his youth. His father owned "Moon Café" and had a go-kart track he called "Moonza", a pun on Monza. Dean was involved in dry lakes hot-rodding in the late 1940s. He founded MOON Speed Equipment (c.1950) and worked to improve the quality and safety of speed and racing products his entire life.
Russell James Liberman was an American funny car drag racer, nicknamed "Jungle Jim." In 2001, he was named #17 on the list of the Top 50 NHRA drivers of all time. Liberman was known for driving backwards at 100 miles per hour (160 km/h) after doing his burnout.
Competition Cams, Inc., often styled as COMP Cams, is a specialty performance automotive aftermarket, motorcycle, and kart parts manufacturer. The company has five US locations including headquarters in Olive Branch, Mississippi.
Jack Engle was a Canadian-born American hot rodder, camshaft grinder, and engine builder.
A dragster is a specialized competition automobile used in drag racing.
Howard Johansen is an American gasser drag racer. He won the first ever National Hot Rod Association (NHRA) C/Gas national title, at Great Bend, Kansas, in 1955,.
