No Ford engine uses a "jackshaft" in the traditional sense of a separate shaft used to transfer power between the crankshaft and other components like a transmission. The term might be used incorrectly or in a very specialized context. A jackshaft is more common in older machinery and some industrial applications, not in modern automotive engines.
If you're encountering this term in relation to a Ford engine, please provide more context – where did you see this term used? This will help clarify what's being referred to. It's likely describing something else, such as a specific internal component or a misunderstanding.
