Vortec is a trademarked name for a line of piston engines for General Motors trucks. A reciprocating engine, also often known as a piston engine, is a Heat engine that uses one or more reciprocating Pistons to convert General Motors Corporation ( GM) ( is a multinational automobile manufacturer founded in 1908 and headquartered in the United States. This article is about the semi-truck For the North American use of the word see Pickup truck. The name first appeared in 1986 on a 4. 3 L V6 but is now used on a wide range of different engines. A V6 engine is a V engine with six cylinders mounted on the Crankcase in two banks of three cylinders Modern Vortec engines are named for their approximate displacement in cubic centimeters. Engine displacement is defined as the total Volume of air/fuel mixture an Engine can draw in during one complete engine cycle it is normally stated in Cubic A cubic centimetre or cubic centimeter (symbol cm3 —the abbreviation cc, though widely used is deprecated is a commonly used unit of Volume

The Vortec 4300 is a 90° V6 truck engine, replacing the Chevrolet 250 in light trucks and 200/229 90 degree V6s in passenger cars (the 200 and 229 were known as the V6-90, both were shortened versions of the Small Block Chevrolet). A V6 engine is a V engine with six cylinders mounted on the Crankcase in two banks of three cylinders This article is about the semi-truck For the North American use of the word see Pickup truck. The Chevrolet inline 6 of the 1930s through 1970s was the base engine in many popular cars including the Chevrolet Camaro. It is based on the 350 in³ (5. 7 L) Chevrolet small-block V8. Chevrolet (ˌʃɛvroʊˈleɪ - French origin (also known as Chevy) is a Brand of Automobile, produced by General Motors (GM Introduction Chevrolet 's Small-block V8 is a famous Automobile engine The engine first appeared in 1985 with the throttle-body injected LB4 in passenger cars (light trucks and vans had carburetors until 1987). Fuel injection is a system for mixing fuel with air in an Internal combustion engine. In 1991, the limited-edition GMC Syclone featured a 280 hp (210 kW) and 360 ft·lbf (490 N·m) turbocharged/intercooled LB4 with the first use of multi-port fuel injection on a Vortec V6. The GMC Syclone was a high-performance version of the GMC Sonoma Pickup truck. The central-port injected L35 (Vin 'W') debuted in 1992 (where the cylinder block was modified - with the incorporation of a balance shaft), with better breathing for 200 hp (150 kW). Fuel injection is a system for mixing fuel with air in an Internal combustion engine. Another CPI engine, the LF6, joined the rest in 1996, while the LB4 was retired after 1998. In 2002, GM introduced a new multi-port injected LU3 engine, and a LG3 variant appeared soon after. Fuel injection is a system for mixing fuel with air in an Internal combustion engine. This engines origins date back to 1955, when the original Chevy small-block V-8 was introduced.

All Vortec 4300s use a cast iron block and heads and 101. 60 mm (4. 000") bore and 88. 39 mm (3. 48") stroke (bore and stroke dimensions the same as a 350). Connecting rods still measure 5. 7" although the rod journal diameter is 2. 25". 1992-present cylinder blocks used a different timing cover since these engines used a balance shaft (some 1992 production cylinder blocks for the LB4 with TBI induction used the 'traditional' front timing chain cover from the small block Chevrolet). They are OHV engines with two valves per cylinder and are produced in Tonawanda, New York and Romulus, Michigan. An overhead valve (OHV engine, also called pushrod engine or I-head engine is a type of Piston engine that places the Camshaft The name Tonawanda refers to several locations in Western New York. Romulus is a city in Wayne County in the US state of Michigan. Power output of the new LU3/LG3 engines is 180-200 hp (134-150 kW) and 245-260 ft·lb (332-353 N·m).
