I know there is a natural instinct to go for the newest engine design, keeping up with technology an all, maybe even better gas milage, but in this case, as said above, it isn't the easiest fit !
In fact you may need to design new motor mounts, Explorer's might fit, in the header department... not even sure there is a set of headers that will work with 4.6L, another design nightmare, and then the newer transmissions, electronics, and so on and so on !
The 5.0L, is like... the Ranger was designed with that engine in the minds of the engineers, the engine is the perfect size, there are Headers for the swap, Monster Header, and all of the transmissions for the 5.0L can be run without a computer. There are a number of aftermarket engine harnesses to chose from, the best one used to be from Ford, three wire hook up !
A 5.0L will produce as much power as you want, build it for high rpms and it will scream, they do 9 second ETs in Stangs, and then there is the lower rpm approach, build it to run around 3000 rpms all day long.
How much HP are you thinking... have you thought about Torque... torque is the thing that gets you moving, the actual power of the engine, so think about it and compare the two engines.
The main thing to think on are, how easy will it fit, how easy will the wire hook up be, what headers, what trans, will there be enough room for the radiator, and other small things that may pop up. The 5.0L has a problem with the heater housing, what will the 4.6L has interference with the same heater housing; sometimes it is far better to stick to something that works !
AND... when I put a '93 5.0L, in my '88 Short Bed, Std Cab Ranger STX, it was a whole new feel to the truck, and I got better mpg from the 5.0L than I got from the 2.9L that came out.
Read some of the postings on the 5.0L and the 4.6L installs, not only on this site , if there are any, but on other Ranger sites that have been around for a while and I believe you will find the best route to be the 5.0L.
Wondering about the weight, I don't know what the 4.6L weighs in at !
Good Luck with this project, read, look, and read some more, until you know what parts each swap will need, what you will be getting yourself into !
