This factory service and repair manual for the 1999 Chevrolet B7 reduces the choice to two engines of very different character: a turbocharged 7.2L OHV inline-six diesel of 441 cubic inches and a naturally aspirated 7.4L OHV gasoline V8 of 454 cubic inches. Both sit in the cab forward school bus designated B7T042. The manual gives each its own fuel, starting and diagnostic coverage with the specifications and torque values that belong to it, then treats the bus itself as one vehicle.
