Re: NV4500 swap is underway
 

Thanks for the pictures. That is indeed the same the same kit I started without side of the different spline sleeve.

No, I’m not saying it’s not worth the swap. There are lots of people having great luck with NV4500’s. My problems could have been an isolated issue or something related to my driving habits, truck weight, power, etc. The problems with mine not shifting worth the crap after they’ve had mainshaft replacements could be related to the aftermarket parts or maybe the guy I am using to rebuild them is doing something wrong.

I think you did get a great deal on what you got.. Don’t be scared to use it. I personally am getting tired of fussing with these things. If mine craps again, its getting replaced with something else.

Re: NV4500 swap is underway
 

I hear you well im just going to use it the way it is the only thing I dont like is that 10 spline 205 but if replace it with the 27 ill have to buy another sleeve I just dont want to put more money into it plus it feels pretty snug for now ill just have put it on and see for myself first. Thanks for replies

Re: NV4500 swap is underway
 

Hey Larry, where is this place? clos to you somewhere? If he has that many squares, do you recall if he has any good body trim that goes around the two tone and in the back of the cab below the rear window??? (73-80)

Thanks!

Re: NV4500 swap is underway
 

It’s in Canon City but it is closed now. One of the brothers that ran it died and the other brother closed it down. The rumor is he could not find a buyer for the entire yard so they called in a crusher and stared scrapping everything. A total tragedy and waste of hundreds of not thousands of trucks if you ask me. It was without a doubt, the best yard around this area that is for sure.

Re: NV4500 swap is underway
 

:eek: :eek: :eek: :eek:

Are you serious!? They crushed all thos trucks??? That is insane, with it getting harder and harder to find parts how could someone have the gutts to actually really crush them! I vote for a preservation program to save al 2nd gen and square body trucks on this planet! ;)

But honestly, that is a shame, small things like the pedal assemblies, the trim or interior stuff are so hard to come by....

Up in the north east here, they crushed about every old truck there was a few years back, so no truck of any kind older than 15 years or so around here anywhere....

Do you have any idea where else I could find OEM trim for the body and behind the cab? and also the two chrome stripes you have in your grill, haven´t been able to find any for 14 years that I own the truck now...

Thanks for the info (even when really sad) Larry!

Re: NV4500 swap is underway
 

What!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I drove out out in Colorado Springs in August 2013 to visit a friend, and because of your post we went out to Canyon Truck to check it out. I ended up finding a set of power mirrors and some fender emblems for the C10. Sadly I could not bring back much more than that because of limited space in the car. That was an awesome place.

This is one picture I took, I have a few more but I don't want to muck up your thread.

Re: NV4500 swap is underway
 

You must have missed the part about the t-case shifter then :lol:. The main reason you will have a challenge trying to keep your original 205 shifter is because there is no pivot on the adapter between the NV4500 and 205 for the shift lever to bolt to like there is on the SM465/205. That fact won't change regardless if you use the AA 1" spacer or not. See picture below.

One option is to purchase the Advance Adapters 205 shifter bracket that bolts to the NV4500 lid bolts but that bracket is horribly flimsy. In fact, I threw mine in the iron pile because I had my doubts it would hold up for what I do with this truck. That left me with the next option of moving to an ORD twin stick. I was not thrilled about doing a twin stick but in the end I am glad I did. The third option would be to fabricate your own bracket as a homemade bracket can’t be any worse than the AA 205 shifter bracket. The last option would be to do a high dollar cable shifter like the rock crawlers often use. Hope that helps.

Re: NV4500 swap is underway
 

Okay thanks. I do remember your thread discussing the weak bracket but didn't catch why the factory shifter wouldn't work. I understand now. I did read somewhere in these threads that AA redesigned the shifter bracket and is rigid now. I may go that route just because I would really like the keep the factory shifter if possible. If its to flimsy I can always figure something else out or twin stick it.

Have you ever had any experience with the 5thGearrepair.com locknut retainer? I wondered if I could use this? I'm not sure I can if I use the AA spacer between the nv4500 & np205.

Re: NV4500 swap is underway
 

Wait a minute Eric. So let me get this right………….you drove clear across the country to visit a junkyard 30 minutes from my house and didn’t even stop to say hello? :lol: Ah well, that’s alright….. last August our baby was barely a month old and I probably would not have had much time to meet up anyway.

BUT, ya! It sucked, one of the brothers died summer of 2013, probably about the same time you were there. The other brother sent out notices to their customers around September/October where December 31, 2013 would be their last day of business. I caught wind of that through Zoomad75 who is the Service Manager at the Chevy Store in Canon City. Zoomad and another member, Ian, ran up there shortly before they closed shop and went crazy grabbing whatever we could. It is a total classic truck tragedy! Not only is it a tragedy to hear of anybody passing of cancer, it is a tragedy to see all of those trucks get scrapped. As you saw for your own eyes, they were pretty well loaded with trucks…GM trucks, Ford Trucks, Dodge Trucks, old trucks, new trucks, trucks trucks trucks….no more Canyon truck so now we are all ?ucked. Rumors come and go where someone else may fire the place back up but I have my doubts as I went by there last weekend and it looks like it is getting emptied out. It looked like portable crushing equipment up by the building. Sad :whine:

Re: NV4500 swap is underway
 

Well Larry, at the time I couldn't PM you, would have loved to stop by and check out the trucks! Ahhh well maybe next time.

Re: NV4500 swap is underway
 

DL,

I was cruising different sites this weekend and somehow came across this model. I'm not into RC's, but couldn't help to think of your rig when I saw it.

Heck, it maybe yours for all I know. Nonetheless, here you go.

Re: NV4500 swap is underway
 

Too cool.

Re: NV4500 swap is underway
 

That is really cool! Nope, its not mine. I don't have near that kind of talent to build something like that.

Re: NV4500 swap is underway
 

Hey Larry
was poking around on ebay and saw this:
http://www.ebay.com/itm/73-80-Chevy-...16.m2518.l4276
That's your truck isn't it? Seems they "borrowed" your pictures...

Re: NV4500 swap is underway
 

Yeah, that is okay. Someone from Xenon sent a message through Flickr quite a while ago asking permission to use my photos. Although, nobody from JW Custom Accessories asked permission they must have gotten them from Xenon. Thanks for the heads up though!

Re: NV4500 swap is underway
 

More famous!

Re: NV4500 swap is underway
 

I made my own version of the aa bracket. it uses the factory shifter. works great. will have to see if I have any pics of it.

Re: NV4500 swap is underway
 

I would like to see your pics if you can find them. I am wanting to keep my factory shifter when I do my swap.

Re: NV4500 swap is underway
 

Hey larry I know its been a while since the last time but im getting closer to installing my nv4500 and 205 ifinally got clutch pedal assembly got mc installed just got a new flywheel for a 2007 6.0 i dont think i mentioned my 79 k5 has a 08 5.3 so question is what clutch and plate do I need to complete the swap. Alot of people run a old school chevy clutch but im not to sure I been reading alot im kind of confused. According to the forums the 6.0 flywheel makes up the gap on the crank on these ls engines but I run a clutch for a 6.0 I might have disengage issues not sure what do you think?

Re: NV4500 swap is underway
 

I don’t have the answer to that one buddy. I’m running an 8.1L which is a different animal to the Gen III small blocks where the 8.1L accepts the same ole 12” clutch and pressure plate as any other older SBC or BBC. You’ll have to ask around to someone that has done a NV4500 behind a Gen III small block

Re: NV4500 swap is underway
 

dirty larry sorry to ask such a repeat question ive recently bought an 8.1 and plan on installing in my 97 3500hd that had a 6.5 diesel with a manual 5 sp nv4500, what i gather from reading your build does the swap on require a 8.1 manual flywheel the nv4500 already existing clutch setup or am i interperting it incorrect if so what clutch would i need?

Re: NV4500 swap is underway
 

Yes, the 8.1L will need its own flywheel. The flywheel bolts pn is 12561465 and the flywheel itself is 12582964. 8.1L’s were used in 2001 and 2002 GMT400 3500-HD trucks so I would use one of those truck models for parts look up to compare part numbers somewhere like Napa or Rock Auto between the clutch/pressure plate for a 6.5L vs. 8.1L. I doubt they are the same clutch and pressure plate.

Re: NV4500 swap is underway
 

How do i identify the model nv4500 in my 97 to a 01-02 manual if their even the same. Like bellhousing patterns.

Re: NV4500 swap is underway
 

Larry, did you ever swap out your rear Detroit for a selectable?

Re: NV4500 swap is underway
 

No, not yet. Too many other projects cooking. One of these days tho. Don’t want an ARB but more of an E-locker. Don’t feel like fidding with a compressor and lines. Don’t have much more room under this thing :lol:

Re: NV4500 swap is underway
 

larry if you still have that 2003 bellhousing would you consider selling it?

Re: NV4500 swap is underway
 

Hey Larry, I'm considering an 8.1 swap. I have leads on an entire truck and another lead on just motor cpu and harness, which is a better option in your opinion. The motor is a 1/3 less price then truck with motor. Are there many incidentals that are beneficial having the complete truck?

Re: NV4500 swap is underway
 

Bilfman,

Personally, I would just go after the engine and ECM. There isn’t anything else from the truck itself that you would really need, including the harness. I would not bother with a donor harness from a truck. The best $500-$700 you can spend on a swap like this is starting with a brand new fresh stand-alone harness from one of many harness vendors. Howell has a decent harness although their consistency seems to a moving target as both my K10 and Suburban harnesses were ordered alike but showed up completely different (trunk lengths, etc.). On the other hand, Howell does have a nice ECM tune for the 8.1L with or without electronic throttle. I use 96-00 L29 7.4L mechanical throttle bodies on both of mine.

If you haven’t already, read through THIS thread. I created it to help 8.1L swappers with the basics and slow down on the PM and highjack traffic.

Re: NV4500 swap is underway
 

Awesome thanx for the info, i'll keep the forums posted once the build begins.

Re: NV4500 swap is underway
 

As I read your entertaining and informative threads... I start to forget the information I read earlier. That being said... I recently purchased an 8.1 out of an 04 (maybe 05, have to drive a few hours to get it) with an Allison 1000. I want to ditch the Allison in favor of an NV4500. I'm more interested in getting the later 5.61 1st gear anyway (95 and up.)

Are there any adaptabilty differences to the 8.1 between the earlier GM NV4500 and the later ones?

Thanks very much in advance!

Re: NV4500 swap is underway
 

From what I can tell, the early NV4500 will bolt up but you will need to use an early GM NV4500 bell too which brings up another bag of worms with the slave being on the passengers side. I don’t believe the AA bell that I am using will work with an early NV4500 as their site says 96 and up.

Re: NV4500 swap is underway
 

Oh man this stuff makes me scratch my head.

Thank You!

Re: NV4500 swap is underway
 

AA makes bellhousings for both early and late GM NV4500s. PN 712577 is for 93-95 transmissions and PN 712576 is fit 96 and up. Neither of them are cheap.

Re: NV4500 swap is underway
 

I've seen these. And I appreciate it. Just trying to figure out which transmission I should go for. Are they all internal slaves? In Larry's previous post he mentioned about slave being on the passenger side. Is this internal on the pass side or external?

Re: NV4500 swap is underway
 

93-95 are all external slaves. 96 and up are the unitized slave-bearing.

Re: NV4500 swap is underway
 

93-94 have the low first gear. 95+ have the higher first gear.
93-95 share the same bellhousing bolt pattern. 96+ is different.
So 95 is the year to get if you want to use the factory GM bellhousing with the higher gearing.
if you are just going to use an aftermarket bellhousing then it really doesn't matter.

Make sense?

Re: NV4500 swap is underway
 

Thank you. Much more sense. 95 has the 1st gear I want and an external slave. Thank you.

In your wisdom, do you recommend utilizing an internal or external slave? I realize if the internal slave fails I have to take out the transmission, but is plumbing a set up for an external slave any harder? The ol' SM465 in mine has a mech linkage so I will have to retrofit.

I'm not new to wrenching but I am new to swapping around parts from different years and going from a carb'd straight 6 to an EFI BB. Your knowledge sharing isn't being wasted and I appreciate your time.

Re: NV4500 swap is underway
 

Well as Larry was saying the only problem with using a factory 93-95 bellhousing with external slave is that the slave is located low on the passenger side. In the 90's the trucks switched to drivers side front driveshaft. So its a bit of a conflict having the front driveshaft on the passenger side and the slave cylinder on the passenger side because it sits kind of low on the bellhousing. If you have a god size lift and a not too flexible suspension perhaps it isn't a problem.

The plumbing isn't really any harder. You can use the factory master, line and slave cylinder. They use a unique clip type fittings. But you can buy an adapter fitting made by Russell, or similar, from Summitracing that will convert that to -AN size, in the case that you want to make a custom line or convert and use a different master cylinder.

Re: NV4500 swap is underway
 

Some people have said that the internal slaves have a bad reputation of failing, and then obviously they are a pain to replace. But it sure would make the installation a lot cleaner.

Re: NV4500 swap is underway
 

Thanks very much and I'll take it into consideration. I wonder if they really do have a high failure rate or if it's just the face that the are a PITA to install. Thanks for the time.
