Yep yep. Except for the 32 valve NA V8s. Luckily for this guy, the Essex was ripped off from the GM 3800 used in the turbo Regals of the '80s. Literally built for F/I. And to the folk who are wondering, the 3.9L Essex is a 3.8 with a slightly different stroke that gives it 236ci instead of 232, but Ford just rounded to 3.9L. And in the long run, 40th anni. V6s with the 3.9L will actually be worth something, while the 3.8s are just gonna be V6 mustangs.

 

04s have different computers regardless of 3.8 or 3.9, i would look for anything but an 04
