Keep an eye on the engine electricals. Do you have a working check engine light and ability to pull Chrysler codes? I have a 95 Cirrus with 2.5 Mitsubishi V6. Good power and fantastic mileage when it's running.
These are notorious for computer and distributor problems. The distributor has coil and many other components built in, so failure of any one part means new distributor at about $900 or rebuilt at $250 and up.
Overall though, congratulations! Sounds like one of the nicest swaps since Subaru flat four into Vanagon.
