Magnum 318 / 360 engine

My next project will probably include one of the above engines along with a 46RH /RE trans or? (something with over drive ) and fuel injection. Want to hit a few bone yards in my area looking for the above combo along with the factory computer and associated wiring. My question is; what years cars / trucks should I be looking for? I am looking at early 49 - 55 2 door wagons as my transplant vehicle. I will probably go with a street stroker kit and mild street friendly cam. I want to end up with a daily driver ( A/C, tilt, cruise, etc) that I can take on long trips if and when I want. Any input would be appreciated. John
