A claim of 260 hp from a stock 4.0L Aerostar engine is highly improbable and likely indicates:
* Significant modifications: The engine has been heavily modified with performance parts (turbocharger, supercharger, extensive internal work, etc.) to achieve that horsepower.
* Misinformation: The horsepower figure is inaccurate or a mistake.
To verify the actual horsepower, one would need to see documentation proving the modifications (receipts, dyno sheets) or have the engine professionally tested on a dynamometer. Without such evidence, a 260 hp claim for a stock Aerostar 4.0L is unfounded.
