Chevrolet LT-1
The LT-1 is a Chevrolet small-block engine produced by the Chevrolet Division of General Motors between 1970 and 1972. It was available exclusively in the Corvette and Camaro and was produced in relatively small quantities. It is regarded today as one of the greatest of the Chevy small-blocks, an engine that has been in production since 1955. History Chevrolet introduced the LT-1 in 1970, making it available in both the Corvette and Camaro. It was an optional engine in the Corvette, and available and as part of the high-performance ZR-1 option. Between 1970 and 1972 only 53 ZRs were produced, making it one of the rarest Corvettes. In the Camaro, the engine was available only through the high performance Z/28 option, replacing the engine designed to compete in Trans Am racing's class installed in 1967-1969 cars. The LT-1 had an 11.0:1 compression ratio, Holley 4-barrel carburetor, and solid lifters. For the first year the LT-1 was rated at in the Corvette and in the Ca ...

Carburetor
A carburetor (also spelled carburettor) is a device used by an internal combustion engine to control and mix air and fuel entering the engine. The primary method of adding fuel to the intake air is through the venturi tube in the main metering circuit, however various other components are also used to provide extra fuel or air in specific circumstances. Since the 1990s, carburetors have been largely replaced by fuel injection for cars and trucks, however carburetors are still used by some small engines (e.g. lawnmowers, generators and concrete mixers) and motorcycles. Diesel engines have always used fuel injection instead of carburetors. Etymology The name "carburetor" is derived from the verb ''carburet'', which means "to combine with carbon," or in particular, "to enrich a gas by combining it with carbon or hydrocarbons." Thus a carburetor mixes intake air with hydrocarbon-based fuel, such as petrol or autogas (LPG). The name is spelled "carburetor" in American English ...

Chevrolet Engines
Chevrolet ( ), colloquially referred to as Chevy and formally the Chevrolet Motor Division of General Motors Company, is an American automobile division of the American manufacturer General Motors (GM). Louis Chevrolet (1878–1941) and ousted General Motors founder William C. Durant (1861–1947) started the company on November 3, 1911 as the Chevrolet Motor Car Company. Durant used the Chevrolet Motor Car Company to acquire a controlling stake in General Motors with a reverse merger occurring on May 2, 1918, and propelled himself back to the GM presidency. After Durant's second ousting in 1919, Alfred Sloan, with his maxim "a car for every purse and purpose", would pick the Chevrolet brand to become the volume leader in the General Motors family, selling mainstream vehicles to compete with Henry Ford's Model T in 1919 and overtaking Ford as the best-selling car in the United States by 1929 with the Chevrolet International. Chevrolet-branded vehicles are sold in most autom ...

Pontiac Firebird
The Pontiac Firebird is an American automobile that was built and produced by Pontiac from the 1967 to 2002 model years. Designed as a pony car to compete with the Ford Mustang, it was introduced on February 23, 1967, five months after GM's Chevrolet division's platform-sharing Camaro. This also coincided with the release of the 1967 Mercury Cougar, Ford's upscale, platform-sharing version of the Mustang. The name "Firebird" was also previously used by GM for the General Motors Firebird in the 1950s and early 1960s concept cars. First generation (1967–1969) The first generation Firebird had characteristic Coke bottle styling shared with its cousin, the Chevrolet Camaro. Announcing a Pontiac styling trend, the Firebird's bumpers were integrated into the design of the front end, giving it a more streamlined look than the Camaro. The Firebird's rear "slit" taillights were inspired by the 1966–1967 Pontiac GTO and Pontiac Grand Prix. Both a two-door hardtop and a conver ...

Overview The C4 Corvette represented a clean break from the Zora Arkus-Duntov-designed C3, with a completely new chassis and sleeker, more modern but still evolutionary styling. It was the work of a team under chief Corvette designer Dave McLellan, who'd taken over from Duntov in 1975. In a departure from the fiberglass panels of its forebearers, the C4's rear bumpers and panels were made from molding plastics, a sheet molding compound. The C4 fastback coupé was t ...

Net Horsepower
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other types of piston engines, as well as turbines, electric motors and other machinery. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 2010, the use of horsepower in the EU is permitted only as a supplementary unit. History The development of the s ...
