440 for your 383/400?

I have a 1975 440 with ~35000 miles on it from a Winnebago.I recently acquired a 1963 Dart and want a 383 or 400 to drop in it since it can be done without fenderwell headers. The 440 is a much more involved swap or else I would just use this engine.So if anyone in the Florida region would be willing to trade for a 383 or 400, please let me know. This engine is complete from intake to oil pan, I can supply pics if there is any interest.It is a 1975 440 with 452 heads.Please let me know. Thank you.Tyler
