I have a 2001 Concorde, 2.7 with 72000 miles.A few months back the water pump failed while my wife was driving. She did'nt notice the temp gage going to HOT and over heated the engine, blowing the head gaskets in the process.I've tried to save the engine to no avail. Too much damage was done. My question is, since the 2.7 is such a lousy engine. Is it possible to up grade to a 3.2 or even a 3.5. And if so what all would have to be changed? I have too many new parts in this car.I basicly have no choice but to drop an engine into it. But in doing this I want it to last.
Your help in this matter is greatly appreciated.
