Stay away from the 6.0L diesel.

The 7.3L is a great engine for about 350,000-500,000 miles. Beyond that it will be pretty tired.

The 6.8L V-10 is a high speed revving engine. It likes to be wound up tight. For those of us who earned our stripes on engines that redlined at 2100 RPM's it is a bit disconcerting to see an engine not start to pull until it is above 3500 RPM.

The 7.3L will see fuel mileage in the 8-12 MPG range.

The V-10 will see fuel mileage in the 8-12 MPG range as well.

At the end of the day you need to decide which will work the best for you.

In the bus world at one time 90% of all light duty bus chassis were Ford with diesel engines.

Today 90% are on GM chassis with gas engines.

No.

Gas engine has way more parts to break, cause issues.

The lack of torque will get old fast. Torque is what moves big objects.

I'm a Ford man from way back and (in my honest experience) for pulling you DON'T want the V10 gas engine. It was designed for high revving and having fun, but not very good for heavy work and longevity. I drive an F250 with a 6.0 every day, a minimum of 150 miles a day. It pulls like a hoss, and with half a million mile on it the only "major" repair was having the injectors replaced a couple of years ago. The 7.3 was a good motor, but less power and worse fuel economy. The 6.0L can easily be beefed up with nothing more than a chip, and it'll pull Stone Mountain if you can hold traction.

IMHO

6.0 first choice, 7.3 second choice, and if you are left with the only option being the V10, wait till you can find something else.

the 6.0's in these buses are not very popular with school maintenance yard folks. When the 6.0 buses hit the auctions they have an actual warning note that reads something like "unless you are a mechanic totally familiar with the 6.0".
I'm sure if you get a "good" one they are great but they are ONLY in existence to meet epa regs. Ford and International "broke up" over this engine.
