Sanity check re engine swap options/planning

Just a quick update, and not sure if this makes anyone's advice/thoughts any different, but the extra transmission I got included in the deal appears to be a 727 torquelite from a 66 Fury. I know that's a very highly thought of tranny so I would assume it makes sense to use that along with pretty much any engine that will match up (as always, please feel free to tell me I'm crazy).
