* Specific model: Chevrolet didn't make a "conversion van" itself. They made the chassis (like a van chassis for the G-series vans). Conversion companies then took these chassis and added the conversion features (interior, windows, etc.). Different conversion companies had different designs and used different materials, affecting the final weight. Even within a single company's models, weight varied year-to-year and by specific options.
* Engine: Different engine options added or subtracted weight.
* Features: The number of seats, the type of interior finishing (wood, carpeting, etc.), the presence of features like a raised roof, and extra amenities all impact the van's overall weight.
Therefore, there's no single answer. You'd need to find the specific make and model of the conversion van (e.g., "1997 Chevy G20 conversion van by [conversion company name]") to get a more accurate weight estimate. Even then, you might need to consult a vehicle identification number (VIN) lookup service or the original documentation to find the precise weight.
A reasonable guess for a *typical* 1997 Chevy conversion van might be in the 4,500 to 6,000 pound range, but this is a very broad estimate. It could be considerably lighter or heavier depending on the specifics.
