Default 98 4.0 ohv replacing 94 4.0

Hi all, been a long time since I've posted here.

All helpful advice appreciated!

Anyway. I had a 93 4wd long bed that I sold and now have a 94 super cab. It had a bad M5OD that we swapped out.

I have Low mileage 4.0 from the wrecked 98 donor truck (62,000 on the OD)

So far with my own research, I've found out that the 98 Exhaust manifolds will probably be ok on the 94's Y pipe.

Swap older wiring harness to newer,

The lower intake manifold? same.. just change the plastic upper to the older aluminum intake plenum?

Use the older fuel rail? newer injectors may or many work?

DON'T use the Cam position sensor,

Anything else?

Assuming most of the bolt on stuff (ac, alt, ps, etc won't change)

I'm paying to have this done so the more advice and prep I can do (with help) the less it should cost me. The shop doing my work is pretty sharp but I don't want a long list of nickle and dime "gotta do's"

( IKnow about the flywheel bolts. will be getting a new FW, and clutch for this.

take all of the sensors from the 94 and install them on the 98 engine any that are not on the 94 you won't need
roscoe
ps just set two engines side by side and make the 98 look like the 94 did

Thanks Roscoe as I mentioned, we're not going to be doing this engine swap when we did the transmission swap it near killed me, and I know it was hard on my friend Hank we're both pushing 70 LOL.

I know this shop does this kind of stuff he was telling me about his daughter's Mustang where he put a later model engine in
