hey everybody, i got a 2005 f250 5.4. im tired of the lack of power. ive looked into chevy and dodge, but still like the ford. i cant decide whether between a used 6.0 or a new 6.4. how is the 6.4 doin as far as mileage and reliability. any input is appreciated. thanks

 

Try looking in the 6.4 forum.

 

From what I hear it is a heavy pig and sucks on fuel mileage. Maybe thats why Ford is in development of there own in hous diesel.

 

Maybe you should look at a V10.

 

I have heard lots of good things and not to many complaints but yeah check in the 6.4 forum

 

7.3 is where its at!!!!
