Will a ford duratec 3.5l dohc 24v v6 mate with Ford Ranger 5-speed manual transmission?
No, a Ford Duratec 3.5L DOHC 24V V6 engine will not directly mate to a Ford Ranger 5-speed manual transmission without significant modifications. The bell housings and input shaft dimensions are incompatible. They are designed for different engine and transmission combinations. You would need an adapter plate, custom driveshaft, and potentially other modifications to make such a pairing work, and even then it's a significant undertaking requiring specialized expertise.
