My brother in law has a 62 Valiant and we've been going back and forth on what powerplant to put in it. Just to put an LA318 requires ditching the heaterbox and other cutting. It finally came to me last night. A 3.9 V6 5spd from a Dakota. Most likely a magnum. What has to be taken from the doner vehicle and how hard would it be to wire it to the car if we can find a doner cheap enough. Thanks
