Who’s still using a 7.3 diesel truck
Who’s still using a 7.3 diesel for there TC? How long have you had it? What TC do you have? What’s are some of the must haves to keep it chugging along happily with TC on top? Cheers

A new Ford diesel the 6.7L engine is and old gasoline converted block that was put in the Ford 392 cu-ft engines in 1962. The International 7.3L diesel was designed from scratch as a diesel engine. The torque delivered is sustained power even under max load whereas the new Ford engines only deliver instant and temporary power and cannot be sustained which is whats make the old 7.3L a better engine to begin with for diesel power.
There’s no much misinformation and outright lies in this post I can’t believe my eyes.
Ford did not make a 392, in 1962 or ever. The 6.7 diesel has literally nothing to to with any ‘60s Ford. They are not derived from any old gas engine at all.
Ford built a 391 FT starting in ‘66. That’s the closest thing to your fictional 392 cubic FOOT (LOL) 6.7 ancestor.
can tell you more about FE and FT Ford engines than you wanna know.
I can only imagine you’re assuming that since the 6.4 was 390 cubic inches, it had anything to do with the old 390 gas Ford, which it did not.
And the 6.7 isn’t even based on the 6.4 it replaced, it’s a clean-sheet ground up new engine.
And it can sustain full power for extended periods every bit as well as a 7.3.
The main reason a 7.3 can do that is it came detuned for low power, so it was understressed. A 6.7 at half throttle will make what a 7.3 did.
Don’t get me wrong, I love the 7.3, it’s relatively simple and reliable. You’re just saying things about it that are absolutely not true.
