Default 5.9 magnum replacement compatibility

I have a 2001 Dodge Ram 1500 sport with the 5.9 360 magnum. The current engine does run just not to well, it smokes pretty bad and the previous owner ran it really low on oil so I’m sure the bottom end is trashed. Well I was thinking about pulling one from the junk yard to use while slowly rebuilding this one. My question is what engines would be compatible? I know they used the 5.9 magnums for 95-01 but I am not sure if they are all they same. If anyone could please chime in on this it would greatly be appreciated!

From my understanding any from 95-02 will work you just need to use your centerhead. As the number of sensors changed throughout the years.

What do you mean by centerhead? I am not familiar with that term/ part.

He is posting from his phone, and it doesn't always work as advertised.

Use your intake manifold, there were changes over the years, so, they are not always compatible. Basically, any 360, 93 or newer, will work. (just swap the intake.)

Oh okay, I gotcha. So what about the sensor issues? Would swapping the intake solve that issue, are the sensors he is referring to on the intake manifold?

Also, i read somewhere(do not quote me on this) that I’m 98 they started using a different cam or something along that line to produce more power. Is that in fact true? because I would hate to lose any power even 15-20 hp

Yeah, most of the critical sensors are on the intake. Biggest difference is, in 96, EGR went away, and in 98, the second coolant temp sensor also went away. Some connectors may be different over the years, but, just use your old sensor, and you should be golden.

So far as I know, the same cam was used all thru production..... (not 100% sure on that.) Programming changed in 98, along with how a lot of the interior systems worked. (instrument cluster, and such like.)

Thats probably what they was talking about. So both the egr and coolant temp is located on the intake manifold?

Yep. 94-97 had two temp sensors, 98 and up only had one. 96 and up simply don't have EGR. (so the passenger side exhaust manifold is different as well on 96 and up.)
