The primary difference between V6 and V8 engines is that a V6 has six cylinders, while a V8 has eight cylinders. Both V6 and V8 engines have cylinders arranged in a V-configuration. In this configuration, the engine contains two rows of three or four cylinders that are parallel to each other and extend out from the engine block in a V-shape.Continue Reading
V6 and V8 engines are the most popular configurations for consumer vehicles. These engines are most commonly used in trucks, SUVs, sports cars and luxury cars because they generally provide more power than the I4 engine.
In addition to configuration, it is important to consider engine volume or displacement, typically measured in liters or cubic centimeters, when comparing engine size. Displacement measures the volume of air that the pistons inside all the cylinders displace, which gives consumers a better idea of the engine's size and combustion capabilities.
Not all six- or eight-cylinder engines are in the V configuration. Inline, flat and radial engines are also possible, though only inline six- and eight-cylinder engines are typically found in cars and trucks. In an inline engine, all the cylinders are lined up in one straight row, which produces a powerful engine but usually requires a very large engine bay.Learn more about Engine
The two different types of six-cylinder engines are the straight-six and V6 engines. The main difference between the two is the way in which the cylinders are organized.Full Answer >
Identify a Ford V-8 engine by examining the part casting numbers on the engine's components. The part numbers on the engine block and other components are coded to definitively identify the engine's year of manufacture, intended application and other information. Cross-referencing these numbers with a Ford parts reference can help determine technical features of the engine such as displacement and firing order as well.Full Answer >
General Motors Vortec line of V-6 engines commonly suffer from problems with excessive oil consumption and engine knocking. Knocking problems are particularly prevalent in Vortec engines used in trucks and SUVs built during the late 1990s and early 2000s. Some Vortec V-6 engines also develop problems with their camshafts, though this seems to be more common among Vortec engines used in industrial applications rather than in passenger vehicles.Full Answer >
Ford Flathead V-8 engines were extensively used in automobiles, farm equipment and industrial applications and are likely to be available through scrap yards or parts sellers that specialize in 1930s to 1950s-era parts. The popularity of Flathead engines among hot rod enthusiasts makes them another potential source of these engines.Full Answer >
