Help me Identify what I have!

I have finally gotten a project and it happens to be a 1968 CJ5
The guy who had it before me did some work on it but I am not sure what.
My father thinks the motor is Buic after market. Its a V6 and that's all I know.

It has a 4 bell Holley carb with a Edlebrock intake manifold.

Thanks for any information you can help me with on my Jeep!

 

I see it has a Buick 231.

 

Column is a late eighties Chevy, since the engine has a PS pump, guessing a saginaw box on the front.
Engine guessing an odd fire 231, looking at the distributor and wire spacing.
probably a 390 or 465 Holley carb
Front and rear are probably stock Dana 27 front, tappered axle Dana 44 rear. These should be marked on the center section webbing.
Drum brakes
Xfer is a single lever Dana 18
Looks to be a stock T90 trans shifter.

Looks like someone pulled the heater and reinforced the firewall.

 

not sure but you'd better yank that carb and manifold off and send it to me for disposal. it's for your own good

 

Strange?? That shifting cane doesn"t look like either one of my t-90 shifters (not to say mine havn"t been re-bent a time or six..

 

Engine is definitely a 231 or at least 231 heads and valve covers. The front should be a 27 as the vent is in the housing not the cover. 25's had the vent in the cover. Saginaw column. GM was the primary user of these but also used in Jeep's and other vehicles. It is later model though. '80's or early 90's from the look of the turn signal lever. Could be from an XJ Cherokee as well.

Rear is a 44 of some flavor. Someone added the central venting system from the axles. May have tied in the vents from the transfer case and transmission which would be a good thing. If you can, some pics of the trans would also be helpful in identification.

 

Wow I have posted these pics on 4 other forums and I have gotten more info from you guys in a few hours then I have in a few weeks elsewhere.

I will get more pics when I can. It is currently sitting at my parents house across town.

So now that we have Identified that its a Buick 231 what weight motor oil should I use?
I will be using Amsoil full synthetic Oil & Filter. Could someone Identify what filter would work for it?
Also are the axels any good or just stock crap?

 

I want to work with what I have for now.
I want to get it running well and take it out to the mud hole and put it to work a bunch of times.
When I have a substancial breakdown like a axel break or motor blow up I will do the complete overhaul.
New Axels, Switch to 350 small block, new transmission & lift it up on 44" SuperSwamper TSL Boggers.
So for now I keep what I have.

 

I would not do that to the jeep but it is your JEEP so do as you please. I like the 34x9.50R15 SS TSL route myself. Around our neck of the woods this is a sweet tire. Good luck with what ever you do.

 

TSL's are great but they dont get enough done where I live & play.
Boggers & Vtread tires are really the only thing that cut threw the mud around here.
The mud here is like wet concrete with lead.

 

Why not get a full size chevy with a 350 or bigger in it. You would probably have more fun. The buick 231 OF is a great motor, but not a high rever or high Hp either. You may be dissapointed the first time you take it in the deep mud.

 

When It comes to Mud I actually take it very easy.
I watch all the idots romp the crap out of their stuff and ruin everything.
Me I am like a old man. I will get in the mud but I take it nice and slow because I find it more enjoyable that way.

Back in the day when my dad took this thing in the mud we had no issues.
If we did get a little stuck we just flipped it in 4 & the torque of the gearing in 4 was just tremendous it had no issues.

 

LOL! I've noticed that before as well.

 

That was a response I got on another forum.
Does that sound right to anyone?

 

I have a 1978 even fire 231, I found some place they recommended 15-w40 for oil.

 

Whats the difference between the 231 Even & Off Fire?
Is a change in the weight of the oil gona kill it?

 

anyone?

 

Ok dont make me beg.

 

in a nutshell, odd fire engines resulted from Buick designing a V6 by just removing 2 cylinders from a V8. this puts a couple of skipped cylinders in the firing order. fire fire, skip, fire fire, skip fire fire... gives the engine a bit of a lope.

in the mid 70s when buick was using the engine again they decided to redesign to smooth the engine out. they retimed to give even space between firings.

clear as mud right? more detail here:

Considering your location and not knowing how many miles on engine, I would go with SAE10w30.
