It’s in the planning stage
I probably won’t do it till next year but I’m planning it out… already priced a used throttle body but will now need a new air filter system and other things plus I want to R/R my heads at same time new gaskets port the heads maybe custom valves if available haven’t done this stuff in many years so I’m taking my time.
Got it!
Got it!

I did the swap on my son's 1999 RC Dakota. There is a bit of difference on the top end, but remember there isn't much power to begin with, so you won't feel a kick in the seat change. It's only half an engine.
The two TBs have a mounting tab on the bottom that has a mating hole in the manifold - but they are in different spots for each TB/manifold. You'll have to file the tab off the 4.0 TB before it'll fit onto the 2.5 manifold. Get a big, sharp metal file and take your time. Make sure not to bugger up the TB's mounting surface. With a new gasket it'll seal just fine.

I don't know if pre-00's are different, but when I did mine the tab was on the AIS motor mount/adapter thing(idk what its called) which bolts onto the side of the tb and all I had to do was swap the mount from my 2.5 tb to the 4.0 tb. If I have time today I'll take my tb off and take some pics what I did.
