I liked my 76 better when it had 53's for sure. One person could roll it with out much of a fight. It'll be easy now until I get an engine in it. :lol:

Any progress on this baby yet?

Nope gotta pull the transmission out and look at the clutch. Dunno when that is going to happen with school and work right now.

Well good luck with it man!

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 
Well I got the transmission pulled out of the truck tonight. After looking at the clutch and noticing there was nothing wrong with it I came home and looked at some stuff and I think I have found that the 6.2 will use a different pressure plate than a 350. Im going to pick one up this week some time so hopefully I will be able to get the truck up and working correctly soon.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 
Do you have a 6.2L flywheel on there?

Mattman2010 12-13-2011 09:07 AM

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 
Yes I do. I called the guy I got the 6.2 from and he said that he used his big block clutch and it worked fine. So we got to looking (He works at oriellys) and we found out that the 6.2 and the 454 will use the same clutch and that clutch can also be used on the 350, but the clutch that I have seems to be for a 350 and not used on the 454 or the 6.2. I am going to take my clutch in to see if it is any different than the one they have.

Dieselwrencher 12-13-2011 04:12 PM

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 
How much is a clutch? Seeing how you have it torn apart, you might as well replace it with the correct clutch so you know what you have.

Mattman2010 12-13-2011 04:50 PM

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 
They are $109 for the whole clutch, but as I have told you it is the exact same one that I have currently. I have narrowed it down to not getting enough stroke out of my current setup. My clutch is not in bad shape so I am just going to leave it alone and try to figure out how to get the stroke I need. I may have to move to a smaller bore slave.

1985-GMC 12-13-2011 05:11 PM

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 
Or bigger bore master..

Are you going to try to lengthen your rod on your slave first?

1985-GMC 12-13-2011 08:53 PM

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 
Yeah I was going to suggest that. I'll try to find the thread where someone did a pretty clean job of it.

Yes before I go modifying everything else I am going to try to lengthen the rod and see if that will work. If it doesn't than I will have to find a way to get more movement out of the slave.

That would be awesome if you could find that thread. I have the idea of using the old rod off of the mechanical linkage because it is a 3/8 bolt. Im just not sure how to go about making the adjustment part.

Mattman2010 12-18-2011 09:53 PM

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 
Well I went ahead and bought a new clutch pack for the truck and then put the transmission back into the truck. Turns out it worked the first time, I am not sure why it would not work with the old clutch pack, but it now works. Hopefully it will continue to work.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 
You don't know how irritated i was getting with this thing, i kept looking at the fuel tank and lighter. I was going to burn it down, but decided just to put it back together to see what would happen.

1985-GMC 12-19-2011 12:23 AM

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 
Haha good choice!

I have a little bit of an idea. :lol: I'm glad you got it fixed!

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 
Well today I went to start the truck and it started cranking really slowly and then i tried it again it the starter motor burnt up. So $170 later I got a new starter in the truck and it starts like a dream! I think the old starter was on its last bit and I finally killed it, every once in a while it would turn the engine over very slowly and was hard to start and other times it would turn the motor good. But now it burnt up and the new starter runs like a champ.

Mattman2010 01-14-2012 11:09 AM

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 
I've decided to keep the project, so I dove back into it again yesterday. First thing was fixing my steering box. It blew a seal and so i fixed that but for some reason the seal has already popped again so I am going to just get a new steering box.

I also have decided that 6 tires is just to much. So I took the bed off and slapped some singles on the back. Yes I am using a dually axle with singles on it, the rear tires I believe the rear axle is 3 inches total wider than the front, so about 1.5 on each side. I dont like how the rear tires tuck under the bed and the front ones stick out so this should hopefully stick them out and make it look better in my opinion. I dropped my good SRW long bed, but I am going to see if I cant bend the parts that are folded in close to where they need to be for now and then maybe find a whole new bed or a good bed side.

I was out seeing if I could tell a difference with the singles. I guess it helps not having the bed on so it road smoother and I decided to do some flexing.

So sunday I am hoping to get a new steering box and get the bed on. Then put my dynamat in the truck and get some heat in it finally.

It was under 20 degrees. But for some reason I wasnt cold just wearing a jacket, I guess fighting a bed for 2 hours warms you up pretty good! haha

Couldnt let you have all the fun working on your crew cab. I agree man I do need some lift. But I am going to get it to a drivable state before I worry about that. A guy I know that has about 30 of these trucks and parts them out is going to look at a burb tomorrow that is said to have a good red interior. It even has bucket seats. So if he picks that burb up I might just be getting me a interior. Red wont be what I want, but if I can get it for the right price it will work till I can afford to put money into it.

I already like it. As you know I wanted a SRW long bed crew cab when I bought the first one and I have done a complete 360 in my planning. I really think I will like it. The dually was cool, but srw will work best for me.

Well I got some stuff done today. I did not end up getting a steering box today and it wont be in till Tuesday so the truck is not drivable right now. I did get the SRW box on today. Its not great but for now it is a bed and it will work.

And if you are wondering how it looks with singles on a Dana 70 HD dually axle here is a picture.

http://i167.photobucket.com/albums/u...b/IMG_0484.jpg

As you can see I believe it sticks out about 1.5 inches. It kind of looks weird, but I think when I lift the truck 6 inches and put some 37s under it the big meats will look good on there.

cletis 01-15-2012 09:01 PM

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 
Tuck looks good, IMO it will look great with fat meats under'er. Ever time I see a truck with stock tires it looks like the rear end is narrower than the front.

joe231 01-15-2012 09:05 PM

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 
Nice!!

I want to swap a DRW diff and front hubs onto my crew so I can run H1 Double bead locks with no spacers...

Thanks man! Yeah I think it will look great setting on some 37x12.5x16.5 inch tires. As for the stock tires, yeah the single rear wheel axles are not as wide as the fronts. That is why I kept the dually axle under the rear, its Wheel mounting surface (WMS) to WMS is 3 inchs wider so i think it looks better with the wider rear.

Yeah I want to find a DRW D60 just so I can do that same thing. But I also have some cool 16.5in wagon wheels that I think would look cool on this truck.

1985-GMC 01-15-2012 10:22 PM

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 
Hummer tires will look sweet on it with your wide wagon wheels!

Mattman2010 01-15-2012 10:28 PM

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 
Yes it will. I just gotta find some 6 inch lift springs for the front and do a poor man shackle flip in the rear. And fix brake lines and steering.

1985-GMC 01-15-2012 11:01 PM

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 
I would go for a 4" lift, I think 6" will be too much and get to be annoying getting in and out of every day. To tell the truth if I could do it over I would order a 2.5" lift for my gmc, it already sits higher than the blazer does with 40"s and its only on 33"s. :\

What color do you plan on painting the wheels?

Mattman2010 01-15-2012 11:22 PM

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 
I dont think a 4 inch lift will clear enough for any flex if you drive offroad at all. I don't want to cut fenders. It might get annoying jumping in there all the time but I think I can manage.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 
That looks really close to the fenders. I would rather be safe than sorry. Ive talked to several people that ran 4 inch and 37s that have said at full lock they have gotten into the fenders.
