This factory service and repair manual for the 1983 Ford LN700 documents a short-conventional straight truck, in a single Base trim, with three naturally aspirated V8s: the 6.1L (370 cu in) and the OHV 7.0L (429 cu in), each listed for propane or gasoline, and the 8.2L diesel (501 cu in). Because the fuel systems differ so much between the three, the manual's procedures, specifications and diagnostics are organized by engine, with wiring diagrams and torque values for the shared chassis.

Known issues on the 1983 LN700. Although the federal record stays empty for this model year, the LN700 carries a long enough engine list to keep a technician busy: the same three V8s as the year before, with the 6.1L and the OHV 7.0L able to burn gasoline or propane and the 8.2L running as a diesel. A vocational straight truck in short-conventional form spends its working life on stop-start delivery and municipal duty, so brake, axle and driveline procedures earn as much use as anything under the hood.
