is the 2004 f250 5.4 260 hp or 305 im deciding on whether to get this truck or wait until i see a v10 but if it has 305 it will make a big difference

 

260hp. I think the SD trucks got the 3V 300hp engine in 05.

 

I too think that the 3v motor came in the superduties in 05, and the 04 still had a 2v.

 

Correct 3V's started in '05 MY for SD's.

 

Up to 04, the 5.4 only had 260 HP and more importantly 350ft/lbs of torque. In 05 the HP jumped to 300, but torque only got a 15ft/lb bump to 365. Woop-de-do.

The V-10 up to 04 had 310HP and 425 ft/lbs of torque and the mileage in a Superduty isn't much worse than the 5.4 from reports around here. In 05 it went to around 352HP and 450ft/lbs.

im going to just back up what everyone else said...the 3v came into the in 05... as far as MPG...my dad cant break 11 mpg in his v10 where as i just got 13.5 with mine and that wasnt ven babying it...we drive the same route all week....if you tow heavy loads...yes wait and get a v10, but the 5.4 is a solid motor even though pre-05 models were a little under powered...as a everyday driver and a once in a while tow-rig, the 5.4 is a great little motor...paired with 4.10 or 4.30 gears it would do just fine...keep us posted!!!

 

1999-f250/f350 5.4 (2v) - 235hp and 335 ft/lbs
2000-2004 f250/f350 5.4 (2v) - 260hp and 350 ft/lbs
2005-2008 f250/f350 5.4 (3v) - 300hp and 365 ft/lbs

1999-f250/f350 6.8 v10 (2v) - 275hp and 410 ft/lbs
2000-2004 f250/f350 6.8 v10 (2v) - 310hp and 425 ft/lbs
2005-2008 f250/f350 6.8 v10 (3v) - 362hp and 457 ft/lbs

 

That looks like a good old wiki quote, the SD's never had the NPI 5.4L's so the '99 numbers are wrong. Not to mention I have never heard of NPI V10 heads which is what that 275hp number must be trying to say.

 

actually i pulled that information off of about 4 or 5 websites...maybe im wrong ... maybe im not but

 

from what i understand the 5.4 and 6.8 motors didnt recieve PI heads untill the year 2000..

bbender85 has a 99 and he claims he doesnt have pi heads either...maybe hes wrong too...

 

Wow thats one way to pad posts. I stand by no NPI 6.8L's or 5.4L's in SD's.
