sweeet.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Well I got both of the fuel tanks on and got all of the fuel system hooked up. Was having trouble with idle so I went back and found some vacuum lines not hooked up so I plug some and hooked others up and it runs great!

Next thing will be changing out all of the fluids and putting the bed back on so that I can use this truck to haul another crew cab 1 ton home to get the 6.2 out of.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Cool, good to hear that it runs great now!

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Yeah when I first had it running I was afraid something was wrong. But the carb rebuild seems to have done its job.

My fuel tank selector sounds like it is having a hard time switching between the tanks. I have never had one of these so I am not sure if it sounds normal or not. It works, but sometimes you cant get the tanks to switch, but if you don't switch it for a while and then switch it, it works.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Does this truck have egr? if so can you show me a picture of how its hooked up?

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Yeah, it has all of the emissions stuff. The thing is there is so much that idk that a picture will show much. I'll try to get a picture the next time I am messing with the truck.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Sorry Matt Man, I have not gotten around to getting that picture for you. I have not touched the truck, I have been trying to figure out the heating problem/oil leaking problem on my k10.

Plans have slightly changed for this build. My lead on a title-less crew cab with the 6.2 diesel in it, and the cab I wanted to use to cut up to fix my rust problems on mine was sold. I did find a guy that is going to be selling his 6.2 diesel out of his truck that he uses to tow with. It is out of a military truck and has less than 60k miles, he said he would give me the radiator, new glow plugs he has for it, fly wheel for a sm465, the oil cooling lines, basically everything needed to just drop it in, and wire the engine up. I think I might be trading him my big block for it.

So for now I will be converting it to single wheel, I kinda like single wheel crew cabs. I don't need a dually, and I cant afford 6 tires for the truck, I am going to keep the bed and the rear axle for now, just encase I want to swap it back to a dually.

So the drive train will be 6.2l diesel/SM465/NP205/Dana44 front/Corp 14 bolt rear.

I was trying to get my K20 parts taken off the frame, but the flat bed is welded to the frame and I ran out of acetylene for my torch so that will have to wait. I think I will start tearing down this truck within two weeks. Should be fun!

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

no problem, looking forward to your build.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Well I have yet to touch the crew cab, I have been trying to get all of the parts I need for the 4x4 swap off of my k20. I got the Cab/Flatbed removed from the k20, and was able to get the front axle off of the frame today.

I am having some problems figuring out how to get some things to work. I was looking at the crew cab frame and the shocks are mounted on the inside of the frame, where as the Corp 14 bolt that I have on my k20 it has the shocks on the outside of the frame. The 1 ton does not have any mounts on the outside of the frame so Im not sure what to do about it yet. I guess I will figure that out when it comes time to mount it up.

I am also wondering about the engine cross member I am not sure if the front of the k20 frame and the front of the c30 frame are the same height so Im not sure if I will have to run some spacers or not.

I plan on running both a front and rear sway bar if they both bolt up.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

I have run into that problem before. The 1 tons and 3/4 tons have different spring mounts. We cut the spring mounts off the axle and rewelded them where they needed to be for the 1 ton frame.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Im talking about the shock mounts. To solve the problem of the spring mounts I am taking all of the spring hangers off of the k20 frame and going to put them on the c30 frame.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

So the past few days I have been busy working on getting the 4x4 stuff off of the K20 frame so that I can mount it to the crew cab frame.

Front body mount/spring mount

All of the parts, Rear axle spring hangers, front axle spring hangers/body mounts, engine crossmember, ect.

Here is the corp 14 bolt I am putting in place of the Dana 70HD

Now I am going to start mocking up the stuff to make sure everything is going to fit, then I will tear it down and paint the stuff and install it for the final time.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

You've been busy! Save your 2wd steering box encase you ever want crossover steering.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Yes I have, lots of using the cutting torch, angle grinder, and chisel and hammer. I am keeping my 2wd steering just for that, after I get this rear axle mocked up I am probably going to remove the rest of the body and the drive train. Then I can start on the front and then start getting things painted!

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Good deal!

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

So this long weekend has been very productive for me. I got the dana 70hd out yesterday and was able to get all of the brackets bolted to the c30 frame from the k20 frame for the rear axle. I used the 1 ton springs and mounted them to the 14 bolt.

Well I know everyone likes pictures so here are the pictures.

Next thing is to pull the engine/front clip/cab and convert the front to four wheel drive. Then it is time to tear all the stuff off and paint it.

I am going to go pick up a SM465 manual transmission to put in this truck as I have a NP205 for one. So far things are working out pretty good, I have ran into some problems but I think I have found out ways to fix them.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Well I cant seem to keep my plans for very long. I am going to be making it back to a dually. To do this I am going to be moving the spring perches over to fit.

The guy that I am going to be getting the 6.2l from also has a TH400/NP208 that I am going at get so that I can keep it an automatic.

I got the front clip off and started to get the 454 unbolted from the truck. So before to long I will have the engine out and the cab off to get it converted to 4x4.

I am probably going to be finding a new cab to put on here as the one I have turns out to have more rust than I thought it was and it wont be worth trying to fix it.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

I got the 454/TH400 pulled the other day and split them apart. I guess when they rebuild the transmission they also put a new Torque convert on it. It was a pain trying to get that thing out, if I tried to lift it above the motor mounts it would hit the hydro brakes but we finally got it out of there.

Pictures!

Now its time to clean up and move some stuff around so that I can pull the cab off.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

nice work!
I can't wait for the 4x4 conversion ;)

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Lookin good!

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Thanks guys, Cant wait to get it running. I just got a new air compressor hoping it will help with sandblasting parts and painting the truck when it comes time.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

This things gonna be sweet once you get it all done with a Cummins in it!

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

I wish I could afford a cummins, I am just going to swap in a 6.2L diesel in for now till I can get around to affording a cummins to stick into it.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 

Here's a few pics of the truck I gave up to before starting my new project. Like I said, I was just getting to the point of going overboard with it - like tearing apart a 4k mile engine to basically turn it into a race car.... The Cummins was great though & loved it while I had it!
