Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1978 C35.
The 1978 GMC Truck C35 appears in the manufacturer’s archive as a distinct model-year entry, though the available technical brief omits specific details regarding body style, platform designation, or engine specification. Within the model’s documented complaint history—which only tracks 1990 through 1996, peaking at three recorded issues in 1996 and bottoming at two in 1994—the 1978 production year falls well outside the observation window. This chronological gap means the truck’s reliability standing remains uncharted relative to the later period’s narrow complaint variance, leaving its service history to be assessed through means other than this particular dataset.
