This factory service and repair manual for the 1996 GMC W5500 Forward addresses the 435 cubic inch inline-six, a turbocharged 7.1L diesel, in the only chassis it was listed in that year: the low tilt straight truck, trim code W5R042. Nothing else appears on the engine list and nothing else appears on the trim list, which means the diagnostics, procedures and specifications run straight through from the front of the engine to the back of the frame without branching.
