Engine And Transmission And Transfer Case Identity Help Requested

Hello group I recently bought a modified from stock 1970 cj5
The PO did not know much about the original builder so I’m reaching out to find out the details .
I am posting images and hopefully they will be good enough to have the drivetrain identified.

 

So these are the images I was able to get , sorry the tranny is under the skid plate and floor.
Is this a dauntless?
What number transfer case?
Any guess on the 3 speed? Thanks!

 

I would guess that it's Buick 3.8L V6, but I don't know the markings well enough to say more. I put a copy of Joel's casting number doc here:

Here's a thread that might help you. Buick v6 identification

As mentioned, the original equipment transmissions have the transmission type cast into the driver's side of the transmission case. This should be easily visible from underneath the Jeep. A T-14 will say "13-02" or "T-14A". The factory supplied an iron adapter plate between the engine bellhousing and the transmission, which this looks like. Aftermarket adapters were cast aluminum.

You have the factory original equipment transfer case: The Novak Guide to the Dana Spicer Model 18 Transfer Case

The Warn overdrive is an aftermarket accessory that only bolts up to the Dana 18 transfer case.

Kinda think your combo is the factory setup; Jeep 225 cid V6, Borg Warner T-14 3-speed transmission, Dana 18 transfer case.

Jeep bought the design and tooling for the 225 from Buick in the mid 60s, and used that engine for CJs through 1971. Buick bought back the design and tooling and started to sell their cars with this engine in the mid 70s. You could have a later 231 cid V6 from a Buick passenger car; they would be a drop-in replacement for the original Jeep 225. Check the casting numbers in the document I linked.

 

From the distributor cap and heads, it looks like a late 70's/early 80's even fire 231. As Timgr says, it's a bolt-in.

It has to be a Dana 18 transfer case since it has a Warn overdrive. That's the only thing they'll fit. Since it has the overdrive, it's probably got lower gearing than the normal 3.73s. If it's still factory, it should be a large hole transfer case on a T-14 3-speed. It also looks to have a Saginaw power steering conversion. This is much better than the factory steering setup.

A '70 should have a rear gas tank from the factory, but it looks like a second tank may have been added under the driver's seat.

From the pictures, it looks like a nicely set up Jeep that's in very good condition. Pictures of the axles and brakes would be helpful.

 

Aha, good info!

 

I posted more pics unfortunately not where I wanted them, thanks for your help!
The driveshaft and diff do seem to be off set to the driver side .

 

Definitely a Dana 18 transfer case and Dana 44 rear axle. It *should* be the stronger 30-spline flanged axle. The rear gas tank looks home-made.

A picture of the front axle knuckles would be good. It could still have the original Dana 27, but it may have been upgraded to an open knuckle Dana 30.

 

My under seat tank is now plastic and there is a stainless one under the tub in the rear with a diversion switch and aux inline fuel pump.
Thanks!

 

Great info!!! Thanks so much!!
I had a couple of commandos in the early 80s with the dauntless . I broke a couple of timing chains if I am remembering correctly . Other than that they worked great.

 

It's the original Dana 27. I kinda like the Heim joint setup on the tie-rods.

Also looks like the original 10" drum brakes. Which really aren't bad when working properly.

 

It definitely has a non stock power steering box mounted in front and smaller steering wheels
Also non zirk ball joints.
Thanks for your help!!!

 

One of the pics is the firing order cast into the intake manifold .
Thanks for your help!!

 

Yep on the 10 inch drums , I had them off to see everything a few days ago. Only one leaking cylinder and a detached shoe.
