Does anyone know yet, whats involved, if possible, in transplanting a 5.4 into a 5.0 windsor powered car? The computers are totaly diffent and all wiring i understand, but that aside, will it fit?

The main problem they had with fitting them to barra was the width with heads and anciliaries... the headers on the V8's are actually super short to make them fit, which means no extractors then...

They are fitted to barra from the bottom, and the panels are actually protected with tape or something to stop them getting scratched and scraped by the DOHC heads.

Now compare the width of a Barra Engine bay with the 5.0 bay you are considering, if its bigger maybe, if not, well you are dreamin'!

Hope that helps!

I dont think they changed the engine bay from AU-BA (and AU is no wider than EA) so it should fit....

Apart from the physical dimension problems it is do-able from an Electronics point of view.
The easiest way would be to use a pre- '99 DOHC 4.6 EECV and recalibrate with a TwEECer. This would allow pre-returnless fuel system and will be compatible with the existing crank encoder sensors etc and will allow retention of COP(coil on plug)ignition.Or you could go for an earlier version and use four double ended coils with leads.
