In my opinion Ford has made a giant mistake dropping navistar. Now we may end up with years and years of diesel engine problems because ford is just now making its own diesels for this application, yes i know that they produce other size diesels, but hasnt it been proven that the only reason that the 6.0 had trouble was because ford refused to use the electronic specifications Navistar recomended. now im a ford fan and an IH fan and it just breaks my heart that we are loosing the best combination of diesel truck/engine suppliers
--just my two cents.
It hasn't been proven yet, that's why the 2 companies keep suing each other over warranty costs for the 6.0. I think all these lawsuits are the reason that ford decided it was time to kick navistar to the curb.
... ford refused to use the electronic specifications Navistar recomended.
Kind of interesting isn't it. Ford can tune a Navistar engine for performance modifications, but Ford won't allow their customers to tune the Ford product.

Neither Ford or Navistar want the bill for problems caused by unauthorized modifications to their products.
Much as the Cummins and Dodge arrangement, Fords 7.3 - 6.0 power ratings were promoted on Navistars own website through the end of 6.0 production, so doubtful anything there was without approval.

I agree with what you're saying, but I was under the impression Ford did bump up the numbers in both the 7.3 & 6.0. I thought Navistars approval was really more of an acceptance after negotiations with Ford on what would wear the PSD badge.

The Ford light truck applications of the 7.3 & 6.0 do have differant torque, rpm and horsepower ratings than in the medium truck applications. Light truck units typically had more horsepower and higher rpm ranges and medium trucks had more torque at lower rpms.
Whose to say Navistar didn't design them for the Ford light truck ratings and "turn them down" for the medium truck market?

I wish Ford would offer two engine brands. International and Cat. Ford is making a big mistake if they do drop Navistar. The 6.0 is a durable engine with crappy electronics. They need to just settle this problem and just move on.
its not the electronics, its the failed head gaskets due to weak head bolts and being short changed on head bolts too, that to me is the biggest problem and is not because of Ford, thats all Navistar since they designed the motor.

they do, you just have to buy a 650 to get a cummins, cat, or international
Why does everyone think a cat engine would be the bomb?????
You take a cat engine, build up your front suspension to hold it, then add a new PCM to rev it higher for the 4/5 spd tranny, THEN, see how reliable it is.
The 7.3 and 6.0 were both successful for international in larger trucks than the f-series.
What happens if you'd tune a ferrari engine to run low RPM's for more tourque????
Ford tunes the international into a "powerstroke" engine, higher tourque band to help the tranny stay together, and a wider power band to help the truck power through all the gears nicely.

2002 7.3 PSD 4x4 Nothing out of the ordinary.
I was looking at internationals site the other day, their version of the 6.4 makes significantly less power then the 6.4 PSD.
They come in a few varieties from 200 - 230 HP and 560-620 ft-lbs of torque. They only have a torque/power curve chart for the low end one, its quite a bit different then the PSD power band, thats for sure.
It makes peak torque at 560 ft-lbs @ 1400 RPM, then its perfectly flat till around 1680 RPM then nose dives off and starts dropping very fast, ending with 350 ft-lbs @ 2800 RPM
Peak HP is 200 HP reached at 2200 RPMs, then its perfectly flat all the way to 2600 RPM, then drops down to around 175-180HP @ 2840 RPM
Just going by how the torque and power curves each have this spot that is perfectly flat suggests the engines are artificially limited.
