GM 60-Degree V6 engineThis engine was Chrysler's first homegrown front wheel drive 60-degree V6 engine, and the first V6 from Chrysler not based on a V8. It was designed to replace the Mitsubishi-sourced 3.0 L V6 in the minivans and debuted in 1990.

There are two major variants of this basic design. The smaller 3.3 L and 3.8 L are pushrod engines, while the 3.5 L, 3.2 L, 2.7 L, and 4.0 L are overhead cam. The 3.2 L was dropped after 2001, but Chrysler continues to produce the 3.3 L, 3.8 L, and 3.5 L versions of this engine along with the 2.7 L LH V6. This line is expanded further for 2006 with the addition of the 4.0 L engine debuting in the Dodge Nitro.__NOTOC__

OHV

The original 3.3 engine, as well as the larger 3.8 L variant, are traditional pushrod engines. The 3.3 was introduced in 1990 and was joined in 1994 by the 3.8. Both remain in production today in Trenton, Michigan, and both use a cast iron block and aluminum heads.

3.3

The first of the family was a standard pushrod version with a cast iron block and aluminum heads. It is 3.3 L (3301 cc/201 CID) with a convert|93|mm|in|2|abbr=on bore and convert|81|mm|in|2|abbr=on stroke. The 3.3 got an increase in power of 12 hp (9 kW), for a total of 162 hp (121 kW), in 1994 thanks to a new intake. In 2001, the engine got a Variable Intake System which boosted output to 180 hp (134 kW) at 5000 rpm with 210 ft·lbf (285 N·m) of torque at 4000 rpm. The engine was designed for transverse mounting but was modified for longitudinal use in the LH cars.

Code-name EGA, it is built at Trenton Engine in Trenton, MI. It uses SFI fuel injection, has roller tappets and features forged steel connecting rods, a one-piece cast camshaft, and either a cast aluminum or reinforced plastic intake manifold.

Vehicles using the 3.3 include:
* 1990-1993 Dodge Dynasty, Chrysler New Yorker, Chrysler Imperial, (replaced the 3.0 L Mitsubishi 6G72 engine)
* 1990-present Chrysler minivans
* 1993-1997 Chrysler Concorde/Dodge Intrepid/Eagle Vision

3.8

The 3.3 was bored and stroked (3.78 in/96 mm and 3.43 in/87 mm respectively) to create a 3.8 L (230.5 CID/3778 cc) variant.cite web |url=http://www.jeep.com/bridge/vehsuite.html?app=vehiclespecs&family=wrangler&model=Technical&zipcode=10101&year=2008 |title=Jeep Specs & Upgrades |accessdate=2008-04-16 |format= |work= |publisher=Chrysler LLC] This EGH version is built at Trenton Engine in Trenton, MI.

The 3.8 got an increase in power of 12 hp (9 kW), for a total of 162 hp (121 kW) in 1994 via a new intake system. In 1998 the compression ratio increased for a total of 180 hp (134 kW) and 240 ft·lbf (325 N·m). In 2001, the engine got a Variable Intake System which boosted output to 215 hp (160 kW) at 5000 rpm with 245 ft·lbf (332 N·m) of torque at 4000 rpm.

Vehicles using the 3.8 include:
* 1991-1993 Chrysler New Yorker and Chrysler Imperial 150 hp (112 kW), 213 ft·lbf (289 N·m)
* 1994-present Chrysler minivans
* 2007-present Chrysler Pacifica
* 2007-present Jeep Wrangler

OHC

:main|Chrysler SOHC V6 engineA single overhead camshaft was an addition to the lineup for 1993. Introduced with the 3.5 L engine, this design spawned the DOHC 2.7 L Chrysler LH engine, as well as the 3.2 L and 4.0 L variants. All but the 2.7 and high-output 3.5 (which features an aluminum block) are produced in Trenton, Michigan.

DOHC

:main|Chrysler LH engineThe DOHC 2.7 L Chrysler LH engine was based on this same design, though the bore, stroke, and production site are different.
