AVERAGE STREET ROD WEIGHT
The following charts provide general guidelines to determine the approximate weight of the most popular street rods. Of course, each car is different so it is ideal to actually weigh the front half and the rear half of your vehicle. Average car weights listed are with driver, automatic transmission, small block Chevrolet V-8, full upholstery and all normal street equipment (such as a spare tire and gas in the tank). Fiberglass cars weight the same as steel. Stripped or lightened cars will weight less. Extra passengers will add to the weight.
