Verado engines are available in 250 hp and 300 hp (V8), 350 hp and 400 hp (V10, introduced in 2022), and 600 hp (V12) as of early 2021. In 2007 Mercury Marine began selling its Zeus drive system. [6] Developed by Mercury and its joint venture company Cummins MerCruiser Diesel (CMD), the Zeus drive is a dual-engine pod drive system.
In 1991, GM created a new-generation small-block engine called the "LT1 350", distinct from the high-output Generation I LT1 of the 1970s. It displaced 5.7 L (350 cu in), and was a 2-valve pushrod design. The LT1 used a reverse-flow cooling system which cooled the cylinder heads first, maintaining lower combustion chamber temperatures and ...
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.
Its block was bored out to 4.04 in (102.6 mm) but its 3.31 in (84.1 mm) stroke left unchanged, resulting in the 340 cu in (5.6 L) engine introduced for the 1968 model year. Anticipating higher loads resulting from racing operation, the engineers fitted a forged shot peened steel crankshaft instead of the cast steel unit used in the 318.
The cylinder block is a chromium-nickel iron alloy with a 60-degree design. [ 10 ] : 34 It has a peak gross and net power output of 170 and 155 hp (127 and 116 kW) at 3200 RPM, respectively, and corresponding gross and net torque output of 310 and 290 lb⋅ft (420 and 390 N⋅m) at 2000 RPM, respectively.
The Chevrolet big-block engine is a series of large-displacement, naturally-aspirated, 90°, overhead valve, gasoline-powered, V8 engines that was developed and have been produced by the Chevrolet Division of General Motors from the late 1950s until present.
Other than that, this engine is vastly different from the Gen-1 model. The Gen-1 engine is physically the size of a big-block Ford or GM engine, and is sometimes called a "big-block". The Gen-2 is closer to the physical size of U.S.-made small-block V8s except for the bore centers, which are the same as some big-block engines.
The 250 engine continued to be used in GM trucks until 1984, after which it was replaced by the 4.3 L V6 (essentially a 350-cubic-inch (5.7 L) Chevy small-block V8 with the two rear cylinders removed). It was also used in a number of large sedans by Chevrolet of South Africa until 1982.
