How well do you think that Dynamat helped it?

Mattman2010 · 01-27-2012, 10:37 PM

The dynamat did not kill the sound of the engine by a little there is still a lot of noise, but I have not finished covering all of what I want to. It did kill drone noise which I beleive was the firewall rattling from the sound. It got rid of the high pitched sound tho so it doesn't get as annoying.

Nothing much with the truck lately. Been having some trouble starting it because I think my ignition switch is starting to go bad. At times I will turn the key and get nothing, turn it off and then turn it again and it will turn right over. I have decided that some more things are going to change on the truck. As you all probably know not to long ago I was loosing motivation on the truck when I keep replacing parts well I have came to the conclusion that sense I have as much money into the truck it is time to change things on it that I really want. One of those things is the drive train. The 6.2/Sm465/np208 is a good drive train, but it is just not the dream drive train that I have been wanting. So I have been talking to Dieselwrencher for a while and found out that he had a 94 12v Cummins that he was looking to sell. It will be a while before I will have it because I gotta pay him off and he is going to do some things to it. I then hope to have it swapped in by this summer. These are some pictures that he sent me. Ill let the pictures do the talking.

94 P-Pumped 12v out of a freight liner. Ill be getting the correct parts to be mating it up to a NV4500 and all of that as well.

Haha yup another one of those cummins swaps. There must be a reason for this madness haha. The 6.2 will probably end up turboed and stuck in my k10. I must just like diesels haha.

Thanks man! I cant wait. Depending on what I find for a NV4500 I might end up finding a dodge 2wd one and run it as 2wd for a while and then find a divorced 205. But I think my best bet would be to find a GM NV4500 and put a NP208 behind it. That will allow me to hook up the speedo on the np208. If I went divorced I am not sure how I would end up hooking up the speedo.

1985-GMC · 02-11-2012, 12:34 AM

The same way...

Mattman2010 · 02-11-2012, 12:56 AM

I would need a longer cable tho wouldnt I?

1985-GMC · 02-11-2012, 01:34 AM

They make cables as long as you want, just cut it to length.

STOCKISH · 02-25-2012, 07:46 PM

Looking forward to the swap!

Here are a couple of pics for you on those clearance lights you were asking me about.

They fit on the roof better than I thought they would.

Mattman2010 · 03-05-2012, 08:59 PM

I really like those, I think they will look great on my white truck. I will take a set, add it to the bill.

y5mgisi · 03-05-2012, 09:40 PM

Man! I want a cummins soo bad!

Its taking me a while to pay it off.

Mattman2010 · 03-06-2012, 11:12 PM

4.10s

Good, youl be in good shape with the 4.10s and nv4500.

Personally I would go 2wheel drive trans into divorce 205. Gives you much better drive line angles. Also for the "just in case" I put mine in the center of the truck so my front and rear drive shafts are the same size. Ever blow a rear drive shaft or u joint out, just unbolt the front and stick it in the rear and head on down the highway. Not to mention the shaft length is manageable and does not require a carrier bearing, also a huge pluss in my book.

As far as the 12v. Go for it!! I'm doing one now

Yeah I think the 2wd trans is what I am going to do because I can find them for about $500 and it seems any of the other ones are $700+. I figured I could run the truck as a 2wd for a while til I find the transfercase. As for putting it in the middle that is a good idea. It would be nice to have the same size drive shafts but I am not sure that the yokes on my D44 and D70 are the same.

As for the 12v its happening, just gotta pay it off then go get it.

yjheep · 03-07-2012, 09:53 AM

might be right on that dana 70 is proly 1350 44 is proly 1310. You can buy 1350 yokes for your 44, there around 100 bucks, I would double check your yokes obviously.

Mattman2010 · 03-07-2012, 10:11 AM

Yeah that will be something I will have to look at. If I can get a transmission I plan on just running it as 2wd because I need to get it in there for as cheap as possible and then find all the stuff to make it 4x4.

Roger that, drive line can get expensive quick. Got almost 3k in yokes and 3 custom built driveshafts

Mattman2010 · 03-07-2012, 11:12 AM

Yeah I don't have that kinda money so I'm trying to use as much of what I have to get it working. I'll probably have my rear driveshaft lengthened and the put a conversion ujoint in it to hook up to the nv4500. I'll have to buy steel to build mounts and buy some stuff for the motor. So I'm basically spending a lot and luckly I found a guy willing to work with me so I could make payments on the motor. But it seems like every time I talk to him I spend more money lol

Lol, my truck started as a budget build but I Realy don't know if there is such a thing.... As much as I try and keep it that way. I basically got my 64k mile 12v for free so that helped
