Anyone have a write-up or a good place to view conversion details. I pretty much need it all so any help would be useful

well, my truck is an 89 k5. I am looking around for a tranny so i don't know what year yet. I know i want to go with a manual this time, for reliability and control, etc... I know the 465 swap would be easier but i want the OD that comes with the 4500. I know with the 4500 that I will need to fab a new crossmember but I doubt that can be very hard. thanks

Well a 4500 isnt much harder to swap in then a 465, the hardest part will most liekly be the pedal setup.

Lets start with the tranny:
93-94 GM ONLY has the 6.31 first gear and a .73 OD
95-03 GM and Dodge has a 5.61 first gear and a .73 OD

Then there are 2wd and 4wd versons.
GM 32 slpine 2wd output shaft
GM 32 spline 4wd output shaft
Dodge 23 spline 4wd output shaft
Dodge 29 spline 4wd output shaft
Dodge 30 spline 2wd output shaft
Dodge 31 spline 2wd output shaft


Im assuming you will use a 205? Advance adapters makes a kit to mate it to a 205.

205 originally mated to a th350, in 71-79 vehicles, Male 27 spline input, figure 8 bolt pattern.
205 originally mated to a 465, in 71 to 84/85 vehicles, 10 spline input, figure 8 bolt pattern.
205 originally mated to a th400, 79 to 84/85 vehicles, female 32 spline input, figure 8 bolt pattern.
205 originally mated to a 465 or 400, in 85-91 vehicles, female 32 spline input, circular 6 bolt pattern.

Now what ever t case you pick, theres different options to mate them together.

For a 4500 replacing a 465 the overall length is 26.250", approx. 1" longer.
For a 4500 replacing a th350 the overall length is 26.750"

AA gives you all the adapters to make it work, however mine needed some modification. The tranny x member was an inch or so to the rear. they give you and adapter, but it wouldnt work. I could have either drilled new holes for the crossmember or, fab a different adapter mount, which is what I did. Also I had troubles with the t case shifter adapter. This was in a 72.

Hope this helped a little, anyhitng else and Id be glad ot help.

nice information.....

dont forget if you have a automatic now.. and wanna go manual...
you have to buy the clutch pedal assembly...

that is all that wasnt covered above.... so what do you need for a nv4500 on the clutch side?

gonna need a flywheel ($120 new)
clutch, pressure plate, throwout bearing ($130 autozone new lifetime warr)

Bellhousing?????? which one.. will a smc465 bell work?

hydraulic or manual clutch style?

I just went to hydraulic clutch... so is it the same bellhousing? I thought I read something where the clutch fork is on the opposite side (passenger side) so I dunno...


I do still have the clutch pedal assembly for a mechanical clutch setup.. I have the bellhousing, clutchfork (new), zbar, spring.....

Hmm...so, theoretically, you could adapt a GM 32 spline female NP205 to a GM version, and a Ford 31 spline to a Dodge 2wd, assuming you cut off the yoke. Is this feasible?

No it wont
YOu can get a stock GM bellhousing found in 93-95 GM trucks, but they have the slave on the passenger side, which might be a problem with low lift vehicles.

Theres also the stock GM bellhousing used in 96 and newer GM trucks, but they have an internal slave.

Or a Advance Adapters bellhousing, they have a few different ones.

Or they make adapter plates, which I wouldnt use.

Yes, if it has the circular bolt pattern. You have to add a spacer for the extra length on th einput. OR change out to the short version input.

iirc, the NP241 did come behind the NV4500 OEM.

How hard would it be to swap an nv4500 into a 72 blazer that came with a 3 speed

saginaw that is a 27 spline male output? I obviously have to replace my manual with something else, and if I'm going to spend the money, the NV4500 sounds like a very nice option. Would the adapter from the auto350 work since that is also 27 spline?
