Hey Reese, search 2006 CROWN VICTORIA COYOTE 5.0L SWAP on the internet, you will
come up to an article on the National Speed page where someone described the swap and
what custom bits they need to do to make it work. I can't link the page here. You need the
engine , a 6R80 transmission, ECM, all wiring, custom work the engine supports and
headers. 397.4 HP. Before you get excited, the parts alone will set you back $10K. I don't
know what your budget is. But I assume someone else will be doing the work since you
asked the question. Labor costs especially custom labor is not cheap, maybe another $5K?
Find a good garage mechanic in your area that does custom engine swaps.
