Looking for info on all the differences between the 2 valve '04 and 3 valve '05 V10's? Like, what interchangeability
there is in the hard parts between the versions. Also is there a really good trusted tuner here that can give me
advice on that part of the engine/trans?
We have a 2004 F250 with 125K and no rust. Use it for our farm operation and just love it but would like
more pulling oomph as we will be pulling a 5th wheel long distance next winter.
My grandson is keen on swapping some sort of diesel for us. We've done Detroit 12.7 / Cummins ISX / Big Cam 400 swaps etc
into our Freightliners (a donor truck in background ha) so yeah, about anything CAN be done, but would appreciate input on what
can be done to make the gasser a little stronger first.
What gears does your ‘04 have? The V-10 NEEDS deeper gears (most came with 3.73 gears) to make them a GOOD tow rig. How heavy is the soon to be towed fifth wheel? If you can get the effective ratio to the 4.30 to 4.56 range it will tow much better than the more common 3.73 ever will. I run 4.88 gears with 35” tires which gives it an effective 4.39 gear ratio, which tows our 12 to 13 K lbs TT pretty well. It also has the Banks long tube headers and I run custom tunes from 5Star Tuning (they know the 6.8 very well), I always tow on the 89 octane performance tune. I have about 80K towing miles on this setup.
Free flowing exhaust is very helpful, Banks headers and exhaust on mine. Deep gears as already stated, love my 4.30's pulling my 11k+ 5vr. I gross about 20k and the V10 does well, just returned from a 6 month 14k mile trip and averaged 7.56mpg traveling coast to coast and border to border. 3 valve is good power but a major job to swap one into an 04. Bolting it in is easy but getting all the electronics working is a big job.
I believe I have heard for the 2v and 3v, the blocks are the same and the fact that they are engines made by ford, and that is about where the crossover ends. Very little is interchangeable in terms of engine parts.
