Besides the Ford V10, the other player in the gas bus motors is PSI. They have an 8.8L (540 ci) that can be used with gas, or propane. I am not sure if it can be set up for CNG. This motor is basicly an improved and stroked chey 8.1L and is likely the larger than 8L engine that GM has been teasing. Navistar makes bus chassis's with this motor.
Glad you mentioned this, I posted this in another thread, showing just how usable the power curve of the PSI 8.8 is:
PSI 8.8L
Rated HP: 270HP @ 2600
@1000 RPM: 103HP
@2000 RPM: 215HP
Rated Torque: 565 ft-lb @ 1500
@1000 RPM: 540 ft-lb
@2000 RPM: 564 ft-lb
That's very diesel like. And should have decent service life at such low rpm.
