This factory service and repair manual for the 1983 GMC B6000 has five engines, one body and one designation to deal with. The bus is the cab forward school type built as B6P042, and the engines are the naturally aspirated 5.7L, 6.0L OHV and 7.0L gasoline V8s along with the turbocharged and naturally aspirated 8.2L V8 diesels. A shop maintaining a mixed fleet will meet several of these, and the specifications, torque values and diagnostic routines are broken out engine by engine.
