How much does a 1978 Chevy Van weigh?

A 1978 Chevy van typically weighs about 4,000–6,000 pounds, with curb weight around 4,000–5,000 pounds and a gross vehicle weight rating (GVWR) commonly in the 6,700–8,000-pound range.


The question varies by model; here is a detailed look at weight by configuration and what factors influence the numbers.


Weight ranges by GM G-Series model


Before listing, it helps to know the lineup from that year: GM used G10 (1/2-ton) and G20 (3/4-ton) vans, plus the heavier G30 (1-ton) option. Curb weight is the van’s weight without fuel or payload, while GVWR is the maximum permissible loaded weight. The figures below reflect typical factory ranges for common configurations and can vary with engine, wheelbase, and equipment.



  • G10/G20 (1/2- to 3/4-ton vans): curb weight roughly 3,900–4,800 lb; GVWR about 6,700–7,000 lb.

  • G30 (1-ton vans): curb weight roughly 4,900–6,000 lb; GVWR about 8,000 lb or more, depending on equipment and wheelbase.


These ranges reflect typical factory specs; exact weights depend on engine choice, seating configuration, payload equipment, and optional features such as heavy-duty suspension or air conditioning.


Common considerations for restoration and use


Before relying on numbers for a project or registration, consult the vehicle’s door jamb sticker (GVWR) and the VIN plate, or reference the original GM service manuals for the exact figures corresponding to a specific truck.



  • Vehicle weight variation by configuration: Cargo vans tend to be lighter in curb weight than passenger vans with more seating and equipment; wheelbase options also affect overall weight.

  • Engine and drivetrain impact: A V8 and heavy-duty options add pounds to curb weight and can raise GVWR.

  • Impact on load capacity: GVWR minus curb weight yields payload capacity, typically around 1,500–2,500 lb for mid-range G-van configurations, depending on options.


For precise figures, reference the exact 1978 Chevrolet G-Series documentation or the vehicle’s original specification plate.


Summary


In short, a 1978 Chevy Van’s weight varies by model and options, with typical curb weights around 4,000–6,000 pounds and GVWR generally in the 6,700–8,000-pound range. Exact numbers depend on the specific G-Series model (G10, G20, or G30), engine, and optional equipment. Always verify with the door sticker or factory documentation for the precise weight of a particular vehicle.
