3.8 or 3.9

orangefinfan · June 16th, 2008, 12:58 PM

I have a quick question for you guys...Do some of the V6's have 3.9L or are they all 3.8L? Because I was told that mine was a 3.9 but the sticker on the engine has the standard 3.8L? The guy that posted about his exhaust states he has an 04 3.9L. Thanks in advance

HMUSN · June 16th, 2008, 12:59 PM

yes they come in 3.8 and 3.9 no difference power wise though

DeMello · June 16th, 2008, 12:59 PM

DeMello · June 16th, 2008, 01:01 PM

and if your engine says 3.8 im pretty sure youd have a 3.8 not a 3.9

HMUSN · June 16th, 2008, 01:01 PM

DeMello · June 16th, 2008, 01:02 PM

they don't have a intake manifold that says 3.9.

If I'm not mistaken, but someone correct me if I'm wrong the later months of 03, and 04 are the only 3.9L v6's so it's not exactly different years. There is no real difference besides a longer stroke, and .1L.

Baker do you know they keywords to find it? I tried to locate it but came up with nothing. Is there a link? I would like to find out what mine is.

Baker02125 · June 16th, 2008, 01:58 PM

Baker02125 · June 16th, 2008, 02:03 PM

Avaric3 · June 16th, 2008, 02:47 PM

i hate to say it but i believe your wrong. i have an 04 and i had (fell off) a sticker above my rad that said 3.8. i think only certain ones had the 3.9. but this goes in the group of "why the fword did ford do this?"

04DSGV6 · June 16th, 2008, 08:59 PM

if im not mistaken they were mixing parts in between the transition from 3.8 to 4.0 and I might be wrong but I thought that 3.9 was only offered in 2004.

04mustang232 · June 16th, 2008, 09:09 PM

it is only offered in 04. and the idea of them getting rid of there overstock parts and thus creating an engine inbtween 3.8 and 4.0 sounds good, but im pretty sure the 4.0 is a completly different engine.

HMUSN · June 16th, 2008, 09:14 PM

the 4.0 IS a completely different motor.

itschristorres8 · June 17th, 2008, 12:05 AM

the crank is the same as well as the rods from 01-04
oddly according to FORD 96-00 share the same crank but in 01 they changed...i dont see or know how. when i take out my crankshaft i will compare it to an 01 and see whats different
