The 8.2L, particularly the non-turbo version, were never very big in the HP department. Most of those engines were set up for about 190-210 HP.
If your engine does not have a turbocharger that would be the first place to start.
You can tweak things in the pump to get a little more go out of one of those engines.
The bottom line is if you try to get much more HP out of that engine you spend a lot of $$$ for very little improvement.
It is what it is. And in a school bus that was designed and built to pick up and drop off kids going to and from school, it didn't need to have a lot of HP.
If the requirement is you need to have a bus that is better able to climb hills and cruise at the posted speed out on the highway you would be better off purchasing another bus that can do the job you need done. It will end up costing you a whole lot less and it will also end up being a whole lot less of a headache.
