77 gmc c35 dually 4-53t detroit
 

New thread for my new project. The truck is a 77 crew cab c35 gmc dually camper special 10,000 gvw. It has a 79 brazillian 4-53t detroit diesel 4 valve swapped in. It has a NP 540 main transmission and a 5831 3 spd spicer aux trans. It also has a dana 70hd rear end, hydraboost brakes also. I will post pics of what is done so far. It was propane injected but the tank was braking the bed (120 gal tank) I have since removed the injection. For those of you that have seen my other build this is total different nothing is painted or show quality. This is a factory conversion back in 87 and I'm keeping the same wear it has on it. That said it will not be thrown together just weathered.

Sounds like a cool project. Someday I want to put an inline 6-71 in something. A long while ago, I put an 8v-92 with a 10 speed in a military truck chassis, and stuck an 86 K30 crew cab drw body on it. That was a big mean truck. :lol:

Here are a few teaser pics. My internet has been down for the last 3 days so haven't been able to post pics.

I like this. A lot.

Re: 77 gmc c35 dually 4-53t detroit
 

Wow this is a really well optioned truck too! Looking forward to more on this! I worked on a 6V73 today. Brought me back to the old days. I'd love to run across an old 4-53. I'd love it more if it was a turbo like this one too!

You are correct lots of options. It has functioning AC and had cruise control but I removed it. It had the Bendix vacuum pump I removed it also I will use an electric one for the hvac controls. It had the biggest muffler on it and a noise reduction air cleaner also. I have replumbed the fuel system the right way. I removed all the fuel tanks except the drivers tank. I modified a bbc fan shroud to shield the fan and am putting in a bbc radiator. It had a small rad rigged in with c channel. I raised the aux trans as far up as it can go it was 3 inches from the ground when I got it. Later I will make a new rear cross member for it but for now I just used square tubing. Right now I am fixing all the cut up wiring and removing what does not need to be there. I think so far I have shed about 1800 lbs off it. The propane injection tank was 80% full and 125 gal that alone is a lot of weight. I will get some more pics tomorrow.

O yea this is about the best Detroit I have seen so far and I have been around them a long time. It doesn't leak, starts right up, and has the highest oil pressure I have ever seen one have.

Re: 77 gmc c35 dually 4-53t detroit
 

You can't beat that at all!

Re: 77 gmc c35 dually 4-53t detroit
 

Here are some more pics just about done. I just have to finish the exhaust and a couple little items.

Re: 77 gmc c35 dually 4-53t detroit
 

More pics.

Re: 77 gmc c35 dually 4-53t detroit
 

It looks nice in there. It looks like you're having some nice sunny weather there too?

Re: 77 gmc c35 dually 4-53t detroit
 

That aux box is down there isn't it!

Re: 77 gmc c35 dually 4-53t detroit
 

Thanks. Yes it has warmed up makes it nice to get out and do some work.

Re: 77 gmc c35 dually 4-53t detroit
 

It hangs a little low it was worse it was just 3in from the ground. I have it as high as it will go. I will make a new rear cross member later. It is even with the oil pan so should be ok. Not going to be rock crawling.

The more I see, the more I like it. You must post a video once it runs.

Some more.

Very nice! I bet you get some looks driving it around town. :lol:

Re: 77 gmc c35 dually 4-53t detroit
 

Curious to know what kind of mileage you're getting out of 212 cubic inches of 2 stroke diesel. I know the DD's weren't really known for being fuel friendly.

Re: 77 gmc c35 dually 4-53t detroit
 

Lots of looks when its up high in the rpm. I was getting about 17 mpg but I found a fuel leak so that's fixed. I drive 30 miles a day I filled up on sun and I still have a full tank. Its a 15 gal tank I am guessing 20's. The rpms are at 1900 at 65.

I love that aux box. They always are down low. When you moved it up it didn't mess the driveline angle up to much did it? Not a lot of guys even know what they are anymore. I have a 6x4 in my Dodge 5500. People always look at it weird with the 2 levers sticking up. Anymore most people get lost seeing 3 pedals.
