This engine was Chrysler's first 60° V6 engine designed and built in-house for front wheel drive vehicles, and their first V6 not based on a V8. It was designed as a larger, more powerful option to the Mitsubishi 3.0 V6 in the minivans and debuted in 1990....

History

A single overhead camshaft was a major addition to the lineup for 1993. Introduced with the 3.5 L engine, this basic design spawned the DOHC 2.7 L Chrysler LH engine

The SOHC engine uses an engine block that is very similar to its pushrod ancestors. But the front of the block was modified for the camshaft
Camshaft
A camshaft is a shaft to which a cam is fastened or of which a cam forms an integral part.-History:An early cam was built into Hellenistic water-driven automata from the 3rd century BC. The camshaft was later described in Iraq by Al-Jazari in 1206. He employed it as part of his automata,...

. Since the bottom end was the same, the engine could be produced on the same assembly line in Trenton as the pushrod engine.

1993–97 3.5 L engines are a non-interference engine meaning that the valves will not collide with the pistons in the event of a timing belt failure. The 1998–2001 3.2 L, the 1998–present 3.5 L, and the 2007–present 4.0 L engines are interference designs.

3.5

This 3518 cc engine was a version of the 3.3 but with a larger bore of 96 mm and the important addition of overhead cams. The 3.5 L version has an intake arrangement with two separate manifolds and throttle bodies connected with a crossover valve. This provides better low and midrange torque. The four valves per cylinder are driven by a single overhead camshaft as opposed to the conventional DOHC arrangement for multivalve engines. Another difference with the 3.5 as opposed to the 3.3 is the fact that the camshaft is timed to the crankshaft with a belt rather than a chain. The water pump is also driven by the timing belt on the 3.5, whereas on the 3.3, the accessory belt drives it.

At its debut in 1993, this engine produced 214 hp (160 kW) and 221 ft·lbf (300 Nm) from an iron block and aluminium cylinder heads. The 3.5 L engine was redone entirely of aluminum in 1999 as the EGG high output, producing 247–253 hp (190 kW) at 6500 rpm with 250 ft·lbf (339 Nm) of torque at 4000 rpm. Output from 2002–2004 for the standard output EGJ is 234 hp (174 kW) at 6000 rpm with 241 ft·lbf (327 Nm) of torque at 4400 rpm. Also for 2002–2004, the EGK 3.5 L Special was built exclusively for the 300M Special, producing 255 hp and 258 ft·lbf.

The EGJ was built in Trenton, MI. The EGG was built in Kenosha, WI. The EGK was discontinued in 2004.

The 3.5 L version is no longer in production as of 2011, replaced by the newer Pentastar 3.6 V6
