What bellhousing is this?

I was told it was for a Buick V6, and it came with my jeep. I know the adapter fits my T90, but is this for a BOP v6 or a chevy?

And is it true a jeep 2.5L will bolt to this bellhousing?

Trying to figure out what I got since adapters seem quite pricey....

Thanks!!

 

It looks like a :v6: bellhousing.

 

Looks like the buick v6 bellhousing to me

You guys are too fast!! I was just googling pics now that I had my own up to compare to, LOL!!

 

I copy/pasted from wiki.....

Instead of the standard AMC bell housing bolt pattern, AMC/Jeep engineers adopted the General Motors small V6 and four-cylinder bolt pattern (commonly used with GM's transverse-mounted powerplants) for their new engine, because the new AMC 2.5 replaced the four-cylinder engines that had been purchased from GM; and because AMC continued to buy the 2.8 L V6 from GM until the 4.0 L I6 was introduced in 1987. The four-cylinder and V6 shared the same drivetrain components, whereas stronger transmissions were needed for the new 4.0 L..........


So I should be able to mount up a 2.5 jeep (well, AMC) 4 banger with this adapter, then? Is this simpleton comprehending that right? It wouldn't certainly save me some time, money, and definately frustration if so.

 

Not IIRC. The small V-6 bolt pattern is call the 60deg V. But I could be totally wrong.

 

No. Not with the bellhousing you posted. The 2.8 and many 4 cylinders used the "60 degree" v-6 pattern as used in most transverse mounted gm vehicles. The Buick rear wheel drive (in this case Jeep 225) bellhousing will not work with those. They are not a standard Chev or BOPC bellhousing pattern, they are their own.

 

Won't work, not at all, not even close. What you have is commonly know as the BOP or Buick/Olds/Pontiac bolt pattern. GM Transmission Bolt Patterns

 

So really, the only engine option with that bellhousing is the Dauntless V6? The 90* 4.3 won't work? And the 3800 FWD v6 is a different pattern as well, right?

Why must life be so difficult, LOL....

 

Buick, Olds, Pontiac and Cadillac all have the same pattern - called the "BOP" pattern. This is a BOP bell. Chevy is different. The 4.3L Chevy is the same pattern as a Chevy V8.

The bell pattern of the FWD 3800 may be the same, but FWD applications are a different block design and won't work in RWD apps (or so I've been told - I expect it's true).

Also with the 2.5Ls, there are 3 different ones. There's the 153 cid Chevy that came in some postal Jeeps (basically 2/3rds of the Chevy inline 6), the 151 cid GM/Pontiac "Iron Duke" engine, and the 150 cid AMC. Both the 153 and the 151 have the SBC pattern. The 150 has the same pattern as the 60 degree V6s used in the XJ, S10 and a lot of GM cars.

So,
225/231 Buick/Jeep V6: BOP pattern
4.3L Chevy V6, 153 and 151 4-cylinders: small block Chevy pattern
AMC 150: Chevy 60 degree V6 pattern.

 

3800's were the metric BP. One other option is a 4.1L used in Buick, Olds, Pontiac and Cadillac. Or a 3.2 used in 78/79 Monza, Regal and Century, not really an option in my opinion. Hard enough finding parts for 225, 3.2's have got to be even harder.

 

Would be sweet to add some Caddy class to the ole CJ, LOL....I gotta find the PO....hopefully he'll be back in the spring to haul off my ranger, because the few places I thought for sure that would have the Buick V6 I need surely didn't.

And the prices of adapters to make a different 4 cyl or other V6 work are ridiculous, and I'd be better off and further ahead using that same money on a rebuild kit. So I'm gonna hafta see if this "patience is a virtue" nonsense makes sense and wait for a 225/231....

Thanks everybody!!
