Before the vitriol starts, I said Chrysler and not Jeep. I’m not talking about the ubiquitous continuation of the AMC mill, but the last ditch ride into the sunset for the 1990 3.3l architecture (which later became the high feature 3.5 from the 300m).

The 4.0-liter V-6 was a single overhead camshaft, 24-valve engine, using a semi-permanent mold cast aluminum block with iron liners and cast aluminum cylinder heads, and cross-bolted main bearing caps. The result being 255 hp @ 6000 rpm and 265 lb. ft. of torque @ 4200 rpm.


Debuting in the Pacifica, released in the Nitro shortly thereafter, and lastly seeing duties in the Caravan/T&C the engine was nothing more than a stopgap waiting for the Phoenix (pentastar 3.6).

It’s not common, but has a surprising level of refinement for a 25 year old architecture with good low rpm torque, good nhv, and pretty good mpgs.
