Somebody better not tell all of us that still drive an IDI 7.3 that it is a 100K mile motor, just as the true competition of that motor, ie GM and Ford BB gas motors were in MDT sized rigs, school buses etc. They do not get 250K miles generally speaking. THE T444E was designed to go around 400-500K before a rebuild, same as the previous I6 DT360, same size as a B5.9, and same longevity, but lighter in weight, so more payload for the end user.
The 6.6 dmax, Isuzu wanted it to be a 500K motor, but GM only wanted a 250K motor. If it had been designed to be a 500K as Isuzu wanted, you would have seen a few different HP versions for the NPR, NRR and Fxx series rigs vs the I4/6 versions they have and still are using.
Do not let all them train engines now that V-Motors are bad, and will not last......they do not run inline motors! They run V motors as they are more compact, fit into those rigs better, producing better hp/torque for them vs the I motors.

nobody said it was a 100k engine. International rates the engine as a B10(minor repairs) Life 200k and a B50(major overhaul) Life of 350K engine before a major failure. You should google the topic before you chime in

TWO PEOPLE at least, should read my WHOLE comment. I did say a T444E/Ford 7.3psd is good to 400-500K miles, AFTER I mentioned the IDI 7.3 was a 100k mile throw away motor.....ie the version BEFORE the T444E. V motors, like I or H motors depending upon design, may only be designed to go 100K miles, or upwards of 1million miles in vehicles. It also does not do any good to design a motor to go a million miles per say, if it only needs to last 8 hrs, then literally blows up, such as a bomb rocket motor. Or like the IDI 7.3, if one is driving 10K miles a year, the power ie 135, 155 or 175 hp options is enough to move the upwards of 26K lbs they were designed to do. Granted ALL city work, not freeway work.....
I also stated, some V motors will go millions of miles, such as those in Train locomotives, They do not use I motors like larger trucks. A V motor is a better option to get the total HP etc in the engine compartment of those setups.
