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.

Where! Where! Where! I love 2 stroke Driptroits!

Re: 77 gmc c35 dually 4-53t detroit
 

Coming soon.

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:

Re: 77 gmc c35 dually 4-53t detroit
 

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

Re: 77 gmc c35 dually 4-53t detroit
 

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!

Re: 77 gmc c35 dually 4-53t detroit
 

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.

Re: 77 gmc c35 dually 4-53t detroit
 

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

Re: 77 gmc c35 dually 4-53t detroit
 

I am going to post a video once I get some tires.

Here are some more pics I have been driving it daily runs great.

Some more.

Re: 77 gmc c35 dually 4-53t detroit
 

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.

Re: 77 gmc c35 dually 4-53t detroit
 

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.

Re: 77 gmc c35 dually 4-53t detroit
 

The driveline angles were bad when it was hanging low. Now all the angles are great. Most people think "o is that for your two speed rear end". When you tell them it's another transmission there minds are blown. I like it when I get asked what is in it and I say just a little 4cyl.

Re: 77 gmc c35 dually 4-53t detroit
 

I always get asked about the exhaust brake switch on the shifter. This thing have a 2 spd rear?

Re: 77 gmc c35 dually 4-53t detroit
 

i have toyed with the idea of putting a 4-53t in mine, but they are a pain to find and expensive when you do find them

Re: 77 gmc c35 dually 4-53t detroit
 

How's the 2-stroke running?

Re: 77 gmc c35 dually 4-53t detroit
 

I drive it everyday. I have 9 vehicles and I only drive this one. I just filled up today haven't got fuel for over a week held a whole 23.00 dollars. I need to get a video but with two sticks its a little hard to hold a camera. I put in some 9a90 injectors it had 5a60 injectors in it. It is a lot more fun to drive it plain hauls butt gets better mpg and a lot less throttle is needed to get moving or stay moving. If you don't watch the go pedal and get a little to far in it no one behind you can see where they are going. :D

Re: 77 gmc c35 dually 4-53t detroit
 

Any chance for a Gopro camera mount for the video?

Re: 77 gmc c35 dually 4-53t detroit
 

I do need to do a video I will try.

Re: 77 gmc c35 dually 4-53t detroit
 

Just thought I would share this. I was driving the 5500 up the interstate the other day and I had an 18 wheeler pull up next to me. He hung right there for a couple of miles and motioned me to open the window. The guy wanted to know if the truck was really a twin stick. When I motioned to him that it was it made his day. Its pretty cool running past a trucker that remembers the earlier days.

Re: 77 gmc c35 dually 4-53t detroit
 

I get some of those who cant believe it is really a two stick.

I'm torn between a 6.0L/TH400 or a DD 4-53T/Allison for my 79 C20. I like the fact that it fit in a 2WD square.

Keep the pictures flowing!
