Changing out an older 340 motor to a newer fuel injected 318

Get the wiring diagram and have at it. You will need to use the magnum flexplate because the crank sensor tone ring is on it. You will need to up the fuel pressure to spec for your year engine. 92 to 95 are a simpler system and obd1. 96 to 2002 are obd2 and more complicated but easier to scan and diagnose problems. There was an article in mopar action I believe on a beer barrel 318 install. I have wanted to do one myself but have not gotten to it yet. Good luck, glad your daughter is ok.
