The biggest headache your going to hit is Ford's ability to use a half dozen bell housing bolt patterns. If you're planning on using the original 56 transmission, what ever that is, you'll need an adapter between the FE and the existing bell housing. However, the 56 trannies are pretty weak, so coming up with something that originally bolted to an FE would be a great labor and cost savings device at this point.
