Among the goals for the new engine were increased horsepower, and elimination of some of the problems encountered with the original design, such as head-gasket failures and oil leaks. [31] Winchell first built an engine with displacement increased to 176 cu in (2.9 L), but this only made the existing head-gasket problems worse.
This was Chevrolet's second 4.3L power plant; four other Chevrolet engines displaced 4.3L: the Vortec 4300 (a V6 based on the Chevrolet 350 cu in (5.7 L), with two cylinders removed), the original 265 cu in (4.3 L) V8 in 1954, a bored version of the stovebolt-era 235 inline six displacing 261 cu in (4.3 L), and a derivative of the Generation II ...
The water pump is mounted remotely with an elongated pump manifold that connects it to the coolant passages. Revised oil pan baffles, or windage trays, are incorporated into the LS4 to ensure that the oil sump stays loaded during high-g cornering."
An updated version of the Generation III 3400 engine. It includes a new block, intake manifold, oil pan, engine cover, and fuel system, as well as electronic throttle control. [11] It was built in China and shipped to Canada for installation in the Chevrolet Equinox and Pontiac Torrent. The LNJ makes 185 hp (138 kW) and 210 lb⋅ft (285 N⋅m).
The GM High Feature engine (also known as the HFV6, and including the 3600 LY7 and derivative LP1) is a family of modern DOHC V6 engines produced by General Motors.The series was introduced in 2004 with the Cadillac CTS and the Holden Commodore (VZ).
The High Value engine family from General Motors is a group of cam-in-block or overhead valve V6 engines.These engines feature cast iron blocks and aluminum heads, and use the same 60° vee bank as the 60° V6 family they are based on, but the new 99 mm (3.90 in) bore required offsetting the bores by 1.5 mm (0.059 in) away from the engine center line.
The Chevrolet 90° V6 family of V6 engines began in 1978 with the Chevrolet 200 cu in (3.3 L) as the base engine for the all new 1978 Chevrolet Malibu.The original engine family was phased out in early 2014, with its final use as the 4.3 L (262 cu in) V6 engine used in Chevrolet and GMC trucks and vans.
6.2L fitted to a 1987 HMMWV. The original 6.2 L (379 cu in) diesel V8 was introduced in 1982 for the Chevrolet C/K and was produced until 1993. The 6.2L diesel emerged as a high-fuel-economy alternative to the V8 gasoline engine lineup, and achieved better mileage than Chevrolet's 4.3L V6 gasoline engine of the 1980s, at a time when the market was focused on power rather than efficiency.
