* Specific engine: Ford used different versions of the 5.0L Windsor V8 throughout the years. The exact specifications (cam, carb/EFI, etc.) affected horsepower.
* Modifications: Conversion vans were often modified by their owners or the conversion company. Modifications to the engine could significantly alter the horsepower output.
While a stock 1993 Ford 5.0L might have produced around 210-225 hp, it's impossible to say definitively what the horsepower was in any given van without knowing its specific engine configuration and any modifications it received.
