Apparently, the mechanic and I had a miscommunication about the engine chosen. What I'm actually getting is a 2v 5.4 from a 2003 used vehicle. He swore that a 3v would be no sweat but I think he re-evaluated and figured that a 2v was less of a headache and I fully understand. I'm still waiting for the truck to get back to me to see the final result.

well the mechanic made the right dicision in my oppinion. wayyy to much extra bs with trying to do a 3v converstion, i have the exact engine in mine that he is talking about. And i love the results so far, they will be even better once the tuner is here next week from bill with the custom tunes sent via the internet. Good luck and keep us posted on how it comes along

OK, here's apparently what I'm ending up with....a 1997 5.4L from an Expedition with 71,000 miles on it.
Now my question is....will there be any complications if I want to buy a Gryphon for a '97 5.4L engine that replaced an '02 4.6L? I don't know if this helps but here's what the valve cover sticker reads: 7G896AB Ford Winsor Ontario Canada *963200575* 417 11-15-96 5.4L I just want to make sure that I can get aftermarket parts (underdrive pulleys, intake, headers, etc) and get a Gyphon for this year motor without any conflicts with the difference in years.

I am not aware of any significant differences between those years, although I've never really looked very closely at them. Mechanically, you'll have to break out the diagrams and see. As for the tuning, it's not too huge a deal. A couple light mods and it should be pretty straightforward.
Nice writeup, Dan.  You'll be getting some play money for your efforts.

I am no mechanic but I am now officially ticked off!
After reading various posts from this and other Ford Truck sites, I now know my mechanic does not have a clue anymore.  He simply bit off more than he could chew and is scambling to make this engine run BUT it won't crank up because of the anti-theft (PATS) device. The fuel system is shut down and the mechanic won't believe anything I have read about this issue. He installed the '97 engine, harness and ECM that wasn't equipped with PATS into my 2002 truck that still has the original PATS device installed. Correct me if I read things wrong but isn't this a problem? Doesn't the ECM and the PATS have to communicate with each other in order to start? I need help...more like he needs help. I'm ready to tow this truck back home and try to get it right myself.
