Does ford make a high output 4.0 engine?

No, Ford never produced a "high-output" version of their 4.0L Cologne V6 engine in the same way that, for example, they offered high-output versions of the 5.0L Mustang engine. While the 4.0L was used in various applications and saw some minor variations in output depending on the vehicle and year, there wasn't a distinct, officially designated "high-output" variant. Any performance increase was usually achieved through aftermarket modifications.
