ford decided to put the 3.9 in midway through the year so thas why there is both the 04 3.8 and 04 3.9.....but no difference really at all

no power gains just a last minute change Ford decided to do.

i think this sums it up perfectly
The 04 3.9 is a stroker beast. Don't let that ~.06 liter (Ford rounds up) increase fool you. It will eat you alive. Bad puppy.

I've heard of 3.9s running 12s stock.

I wish I had that .06L

MakeHerScream04 · May 9th, 2008, 12:08 AM

yours doesn't do wheelies, you must have the 3.8

lwhitetrash88l · May 9th, 2008, 01:56 AM

lwhitetrash88l · May 9th, 2008, 01:57 AM

Total Failure...

04's have a 3.9 no way around it...
i like your new car...

and all ford did was use a different rod, or something or other... not like i care... off of a different essex block that was in production to free up room for there new engines being produced
