That's crazy! How did I not know that?The 3.8 feels like a Pentastar with two plug wires missing. It is arguably the weakest Jeep engine of the modern era. I owned two of them.
Let's put it this way: The performance jump from the 3.8 to the 3.6 is as large as the jump will be from the 3.6 to the 392. [not quite, but it feels like it]
