Once I have this information, I can provide you with a more specific list of engines that would be a good fit for your 1984 Ford Ranger.
Here are some common engine swaps for the 1984 Ranger, to get you started:
Gasoline:
* Ford 302 V8: A popular choice, but it may require some modification to fit.
* Ford 351 Windsor V8: More power than the 302, but requires even more modification.
* Ford 4.0L V6: A reliable and efficient option, often found in later Rangers.
* GM 5.3L V8: A modern and powerful engine, but requires a lot of modification to fit.
Diesel:
* Ford 6.9L IDI: A reliable and fuel-efficient diesel, but it's large and heavy.
* GM 6.2L Duramax: A modern and powerful diesel, but it's very expensive.
Remember, any engine swap will involve some modifications and challenges. It's important to do your research and consult with experienced mechanics to ensure the swap is done properly.
