IMRC's were added.

yup.

the IMRCs control where the air flows down in the lower range and open in the larger range

yes, the new 04s are 3.9L they are using the new Freestar's engine trying to get away from the old stigma of the Windstar's engine.

the 3.9 is just bored out a little, i believe. they goto the 4.0 next year though

btw, welcome to the board npassos

yes, the cars that came out in 04 themselves (not the 04s released in sept of 03, etc) have the 3.9. pretty much 2004 1/2 have the larger engine. same hp, but larger engine

Probably had something to do with some extra parts laying around from a discontinued project or in the make of some blocks they were actually overbored. Car companies waste nothing!!!!

i think they just switched over to the Freestar's engine instead of the old windstar's. it may have picked up like 5tq, but ford wont claim it. it would look bad IMO of them if they produced a car that had more power halfway thru a production year. either way, i think it is just slight overboring. enough for them to round up to a 3.9 instead down to a 3.8

first off, if you talked to the guy at the ford dealership on the corner of cooper and I-20 in arlington, they dont know anything (i went to UTA for two years, so i know the area. might be moving back in may)

next, if you want to put a pic in your sig, you goto User CP and put the hyperlink to it. goto a place like www.mustangmods.com and you can host images there. then just put the link in the sig area with
