Fit question: 2000 4.0L fit in a 94 4.0L

Is a 2000 4.0L V6 a direct fit/replacement with a 94 ?

Thanks

Fit............ yes, they are both 4.0l OHV engines, so motor mounts and transmission bolts line up

But there are differences in other aspects
1994 has a 6 bolt crank flywheel/flexplate, 2000 has an 8 bolt crank

1994 used a 30psi fuel system, 2000 used a 50psi fuel system

If you just used the block and heads from the 2000, and used the intakes(both) and exhaust manifolds from the 1994 on the 2000 you should be OK
You will need the 8 bolt flywheel(manual) or flexplate(automatic) for a 2000, they were used from 1997 to 2000 in the OHV

4.0l OHV changes over the 10 years(1990-2000) seen here: https://therangerstation.com/tech_li...0rebuild.shtml

Hey RonD..Thanks for the great response.
I'm a rookie at this, so please forgive my ignorance.
If I did purchase this 2000 4.0L - still in the truck, runs and sounds good - the thought would be to pull the engine from the 94 and drop the 2000 in.
The 94 is my first vehicle that I bought and paid for as a kid. I love the truck, but sentiment has a way of clouding the the senses.

Transmission in both are auto so would what you say about the "6 bolt crank flywheel/flexplate, 2000 has an 8 bolt crank" mean that the transmission from the 94 NOT work with the 2000?

Again, sorry for my dumbness and thanks for your advice.

It would work you just need the Flexplate to come WITH the 2000 engine, the 1994 torque converter will bolt to flexplate

The flexplate bolts to the crank, so 1994 flexplate only has the 6 holes, you need the 2000 flexplate with 8 holes


If this is your first automatic transmission engine match up..............................VERY IMPORTANT
You must SEAT the torque converter inside the bell housing FIRST
Install it on the input shaft, then turn it as you press it in, it will slide in 2 or 3 times, until it is completely inside the bell housing

Then you install the transmission onto the engine, making sure the torque converter doesn't slide out if you tilt transmission
Once the bell housing is bolted to the engine, you can turn and slide the torque converter forward to line it up and bolt it to the Flexplate

I broke my first automatic because I didn't know about SEATING the torque converter, over 40 years ago now, lol, and I broke a just rebuilt automatic, it was a real bummer

Again, many thanks.
I'll make sure to do more research on the procedure to make sure I understand the whole process. Sounds like it is within my capabilities. Just need to go slow with it.

Thanks, I'll keep you posted if I decide the sentimental value is indeed worth it. :)

You will find that pretty much all the wiring for the engine is on the upper and lower intake manifolds, so if you swap the 1997 intakes over to the 2000 all the wiring will just plug back in
You can look at the 2000's intakes and connectors if they match then you may not need to swap it out

Exceptions are the Crank sensor and Cam sensor
Crank sensor on 2000 should have the same plug/connector
The Cam sensor will NOT, you will need to swap over the 1997 cam sensor and tower(synchronizer) over to the 2000 engine, 1997 uses 3 wire, 2000 used 2 wire, different signal types
This part needs to be Timed

Oil pressure and oil level senders on drivers side of engine block should be same plug-ins
