I originally posted this on the Buick FSJ forum with no response, so I will try here.

I like Buicks.
I like Buick V8
I like Buick 350 V8
I like FSJ equipped with a Buick 350
I would like to own a modern FSJ with a vintage setup like a Buick 350.

So, I was thinking. (That always gets me into trouble)
A BOP Bellhousing is not difficult to locate.

I also am under the impression that a BOP Bellhousing would accept a NV4500.

So, if what I believe is true, that a BOP bellhousing will accept a NV4500 or even a NV3500,
then a 5 speed in a FSJ sounds like it would make a great swap!
The gas economy of the 5th gear and low first for crawling and towing. WhooHooo!!

Question:

1. Can a NV 5 speed bolt up to a BOP bellhousing?

2. If this pure fantasy on my part that a NV 5 Speed would bolt up to a BOP, then could it be adapted?
or the Bell welded or machined to accept a NV 5 Speed?

3. What rear end ratio would be best behind a 5 Speed? 3:73?

4. What transfer case would one for a passenger side drop? for a drivers side drop?

wow! Good post. I would love to puot a 5speed behind the Buick350 in my 70. In afct....I personally think it's the best FSJ motor.

However, I don't think that a NV4500 (or any relatives) will directly bolt up to a Buick350. I was under the imporession that 4500s were mainly used behind Ch*vy products and Dodg*s.

But I'm a moron so who knows.

AA doesn't list and Buick V8's so who knows...maybe they do bolt together.

For sure, the Buick 350 is the finest motor Jeep ever used. I have a ranch truck with a buick 350 and T-18 and it is awsome.

The NV4500 has a different, unique bolt pattern but the input shaft length, 6.5" is the same as Chevy. Seems like you would have to modify your bolt pattern and machine the bellhousing to accept the NV4500 input shaft retainer.

You would be much better off with a Ranger OD and T-18.

Thanx.
If machining the input hole in the bellhousing and redrilling and tapping mounting bolt hole is all that is required, then I can have that done!
The input shaft length being the same helps.

But to the top for more opinions on this topic.

Does the back of the NV4500 have the round bolt pattern that is common to NP style transfercases?
If so, the XCase choices are very broad! [img]smile.gif[/img]

Does anyone make a steel "scatter shield" style bellhousing for Buicks? It sure seems like you could find one, and that would be simple to modify for different transmissions.

I know someone makes Chevy-BOP bellhousing adapters. Maybe you can use a NV4500 w/ Chevy bellhousing, and one of these adapters between the bellhousing and the engine. I think they are about $65

I agree!
Yes, Jegs sells a steel "scatter shield" style BOP bellhousing, but they are pricey!



Jegs: Lakewood Blowproof Bellhousings

Olds/Pontiac (which would include Buick)
620-15100 1965-77, All V8, (except diesels) $309.99

The tailhousing on a NV4500 4x4 has the round NP pattern. Almost no stickout. The dodge version is indexed for the ford and dodge tcases and the chevy is indexed different for the chevy tcases. Ford and Dodge largely drop their tcases to the drivers side.

I made a spacer to go between a Dodge HD version of the NV4500 and a BOP Lakewood bellhousing. If I can figure out how to attach a pic here, I will. If not, see this link. http://home.supernet.com/~zmjeeps/FSJ.jeeps/long7.htm
At the very bottom of the page, you'll see the spacer, bellhousing, transmission and bolted to the engine.

Should have noted, the engine pictured is a 500 caddy, but the bolt pattern is the same. The thickness of the adapter may have to change depending on the dimensions on the crank and pilot bushing.

Bryan. Digging up an old thread but..
Did you ever figure this out?
I also just picked up a 500 caddy motor/long tail 400 trans and did the usual googling searches and our site cam up.

I also have a NV4500 that was slated to go into a 77 step van for my business.
But now looking to sell the van and use the 81 Cherokee instead, and maybe the caddy/NV/14bolt/2wd instead of 4wd since I don't think I'd be using that any time soon.
