Both are great engines, but the C7 is going to run circles around the IDI 7.3. Plus, it is 13 years younger so a lot less age related issues on the whole chassis.

Good to know; i wasn't aware the C7 is much superior to the 7.3L. As per the age, the 7.3L hasn't been used much, very low mileage. Used only during summer. That's why I was considering the comparison.

Yeah, but it’s a 500,000 mile rated motor. That’s the average time between rebuilds. The C7 is a true heavy duty motor. It has wet liners meaning an in frame rebuild is possible. It was still a HUEI motor until 2007 so you don’t have to worry about common rail issues. The 7.3 is a good motor, but underpowered for a school bus. It has a history of cavitation issues. The International DT466 would be an equivalent motor in that brand. It’s a no-brainer in my opinion.

Rt...what do you think would be a fair price for the 1992 7.3L?

I don’t have a feel for that. I’d start at about half what the newer one is going for.
