The engines were produced in two major variants differing by their piston displacement: a 3.3 L; 201.4 cu in (3,301 cc) and a 3.8 L; 230.5 cu in (3,778 cc). The 3.3 was dropped after 2010 with the Chrysler minivans, and the 3.8 was dropped after 2011 with the Jeep Wrangler, ending 22 years in production.
This engine used a provision in the rules intended for stock block pushrod engines such as the V-6 Buick engines that allowed an extra 650 cm³ and 10 inches (4.9 psi/33.8 kPa) of boost. This extra power (1,024 horsepower , [ 15 ] which was up a 150-200 hp advantage over the conventional V-8s.
Wards 10 Best Engines is an annual list of the ten "best" automobile engines available in the U.S. market, that are selected by Wards AutoWorld magazine. The list was started in 1994 for model year 1995, and has been drawn every year since then, published at the end of the preceding year.
The roomy LaCrosse is available with GM's proven 3.8-liter pushrod V-6. while the 2009 Ultimate New Car Guide from the editors of Automobile are more specific on page 36: GM's old workhorse iron block pushrod 3.8-liter V-6 pulls engine duty for CX and CXL models, but it is coarse and noisy at high engine speeds.
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.
An overhead valve engine, abbreviated (OHV) and sometimes called a pushrod engine, is a piston engine whose valves are located in the cylinder head above the combustion chamber. This contrasts with flathead (or "sidevalve") engines , where the valves were located below the combustion chamber in the engine block .
The 166 used a slightly detuned version to make more low rev torque. This engine version was awarded as the International Engine of the Year in 2000. [22] The engine has a bore and stroke of 88 mm × 68.3 mm (3.46 in × 2.69 in), the same as the two-valve. Applications: 1996 [24] –2005 Alfa Romeo 156; 1996 [24] –2007 Alfa Romeo 166
The Pentastar engine was introduced at the 2009 New York Auto Show. [2] [3] The engine design allows the use of E85 or 87 octane fuel and features dual variable valve timing. Forced induction, and cylinder deactivation options were engineered into the engine design, but have not been implemented from the factory, remaining "on the shelf" as of ...
