Looking for easiest way to get a nv4500 behind a 5.0HO?

I have seen some hints that I can just remachine the center bore on a np435 bellhousing, but I haven't seen any hard evidence. By the way, the nv4500 I am looking to do this to is a 93 GM. Any help would be greatly appreciated, as I am trying to do this on the cheap.

Thanks,

Ken

you could just sell the NV, and buy a ZF that would bolt right up to it, probably cheaper anyways.

the easy way would be to forget it and go with the zf 5spd. But if you want the nv4500 GM version. then you need a lakewood scatter shield and hen redrill it for the transmission mounting. Its easy becuase you can weld the nuts on the back side after the holes are drilled.

The output shaft spline count will create some difficulty in mounting the dana 20. i think the gm version was 31 spline. you will have to hunt for the spud shaft set up from advance adapters

Because of the 6.34 1st gear?

I have put a 93 NV4500 behind my 5.0 with a lakewood scattershield.
No, you cannot just rebore the NP435 bellhousing because the mounting holes for the NV4500 are too wide, and will not secure to anything. And the GM NV4500 has a 32 spline output, that you will have to modify for the transfercase of your choise
Even the lakewood bellhousing will not come ready for the NV4500. you can order the Bellhousing with any bore diameter you want, but you will still have to transfer the 4 mounting holes to the bellhousing and install a threaded insert to secure to.

Your real problem comes with the throwout bearing. The Lakewood bellhousing will come ready for a Ford clutch arm, and most of the Ford throwout bearings will be too big I.D for the smaller GM front bearing retainer(which the throwout bearing rides on)

Option 1) I found a older Ford Granada(with a 3 speed tranny) that used a smaller throwout bearing. You will have to machine the bearing reatainer on your tranny down to accept the smaller throwout bearing.

Option 2)you can have the bearing reatainer welded up to add material, then have it machined to accept the Standard Ford Throwout bearing.

Option 3) you can adapt(Weld piviot at proper placement) a GM Clutch arm and piviot to the Ford style bellhousing and stay with all GM Clutch parts(Except the flywheel).



I have done this several times and found that the cheepest and simplest way for me was to machine the bearing retainer and use the stock ford throwout bearing.

If you want more information, please feel free to e-mail me at: BBuiltparts@yahoo.com.

I have this complete setup sitting on my bench apart if you need pictures or more clarificaiton.

Are you interested in selling it?

Does Novak make an adapter bellhousing for this? I have contacted AA about it, and they say alot of people just machine the lakewood bellhousing and put it in that way.

What you describe is alot more than what I would want to do, mainly because I don't have access to machines to do it myself. By the time I figured in machine work plus hte cost of the Lakewood bellhousing I would be ahead of the game if I went with an AT or a ZF. I just like the fact that I have a 4500 sitting in the shop already and would really like to use it. Although, I could sell that for 1k and buy a rebuilt C4 for $800 and have enough cash leftover for beer and pizza for a weekend install with some buds.

why is it a bad idea to not just go with a ZF? are they just more pricey? i know they just about have the same granny gear. and arnt they just about the same strength? im just confused on why the NV4500 would be worth it.

Because I already have one sitting in the shop and I know how it is. If I could find someone willing to trade straight up, I would. How ever, if I sell mine for 1k and buy a ZF for 750ish and it needs a rebuild, then it will be another boatload of cash for that. Thus, making the nv4500 cheaper to swap in. Basically, I need a quick easy way of getting my 5.0 into my TJ because the little 4 banger is starting to give up the ghost.

well i understand your situation, but everyone else (minus J-Rod) makes it sound like your just better off with the NV.

I stuck a Dodge NV4500 behind my 5.0 using an F150 bellhousing, adapter from AA, and then made a hydraulic slave cylinder mount.

It was still a cheap & easy way to bolt up a bombproof tranny.
