1985 GMC High Sierra 2500 with 454

[98Murray]

Hello, I am a new member but have been reading this forum for awhile. I am 16 years old and live just south of Dallas Texas. This is my project truck. It has been sitting on the fence row at my grandfathers farm for about 20 years. My grandfather said if i wanted it I could have it so I drug it home a few months ago and started working on it. Its a 1985 GMC High Sierra 2500 2WD with a 454, 4 speed with granny first gear, 4:10 rear end, and a longbed. We used it for a long time out here on the farm until in 1995 the engine started knocking so it was taken out, rebuilt, and installed but never finished. In 1997 my brother who was only 10 at the time decided he was going to try and get it running but the carb backfired and burnt up some things under the hood, nothing terrible tho. So far I only have about $50 invested in the truck and it does run. The carburetor is not correct because it has an electric choke but should have a hot air choke so I need to replace it. Also it needs a new clutch master cylinder and a battery. This has been a fun project and I cant wait to finally drive it. Its not going to be a daily driver but probably just a feed truck used for hauling hay. Here is some photos of the truck and also a video of it running. A friend of mine has been helping me out with the truck and getting it running but most of the work I have done myself. Let me know what yall think of the ol girl. I will post updates and new photos/videos as I work on the truck.

Photos. As you can see I have some other projects as well. BTW I have matching original wheels, the chrome one is just a spare

Looks like you got a good start! Its got a heck of a drivetrain in it! I'm 15, So I know what your going thru, lol I'm building a 86, Check out the build thread in my signature!

Nice truck Hankster. I mocked up a headache rack today and I'm kinda thinking about mounting it. What do yall think?

[Hankster]

Thank you, and I like the headache rack with the long bed!

[98Murray]

Havent been doing much to the truck due to some rain and work but I have decided to mount the headache rack and also a full set of chrome modular wheels since they look good. Gotta clean up the wheels and get some tires swapped over but for now I have 2 on the truck. Also have to get some bolts and a drill bit so I can mount the headache rack.

Whoops. Didnt mean to post twice. How do I delete a post?

How to delete or edit a post, no expert, their is an icon at the bottom of post once posted "edit", that allows you to make changes for 30 mins. after post.

On hyd clutch master cylinder, my truck was in storage for long time and it leaked. I replaced both cylinders, along with line. I needed to bleed new cylinder on firewall before connecting to line going to lower cylinder on bell housing. I bleed mine in the truck connected to reservoir, with pedal rod in engine compartment. I pushed rod in and out until all air bleed out. I then gravity feed the rest of system, not letting reservoir fluid go empty.

Sounds like you have a nice truck, lots of options to work with.

Welcome to the forum! Always nice to hear from fellow Texans. Looks like a pretty solid truck to start with.

[98Murray]

Thanks Flatpat! Nice to see other Texans here too! Well this evening I mounted the headache rack and also pulled the rubber floor liner and insulation to see what damage the bad heater core did 20 years ago. The paint bubbled up and there is some rust but nothing terrible and no holes. I am going to wire brush it the best I can and then sand it good and prime it so that i doesn't get worse, then probably just get some floor mats for it. Sorry about then crappy night time photos, I will try and get some better ones tomorrow.

looks like a solid southern truck, hey does that small trailer self load a round ball just by backing up against it?

thats pretty inginious ! never saw that before altough im not much around farm stuff

[98Murray]

Got a little work done to the GMC today. It is suppose to have a hot air style choke but the carb is a replacement Quadrajet with electric choke but we swapped it to manual choke thinking it would be the easiest way to do it but after messing with it for a few hours the manual choke just wasent going to work so I put the electric choke back on and now I just have to wire it up to a toggle switch in the cab. Also I got some better photos of the floor. Its not really bad on the drivers side, most of its on the passenger side. I think I am going to treat it with some rust converter first before painting it.

[98Murray]

Havent done much to the truck lately because I have been a bit sick and I have to fix up a old tiller so the GMC is on hold for about a week but as soon as I get back to it I am rebuilding the carburetor and putting in a new clutch master cylinder. For now here is a older photo of it

[98Murray]

Did a little work to the GMC today. Got the old clutch master cylinder off and also my mom was nice enough to paint one of my hubcaps that had lost all of its red. I think I will run some of these caps with some black wheels, it looks nice. and yes that is finger nail polish she is using lol I sprayed some clear coat over it.

[98Murray]

I have been doing alot of little odd things to the truck today. Mostly electrical. I got all my lights inside and out working good and once I get a license plate lamp and 2 new headlights the truck will be completly lighted lol.

Thanks and its a 1968. It was my dads old truck and is a slow restoration project.

Got my 6 hole plug installed on the bumper and the newer electrical brake controller installed in the cab. I was thinking about using another Berg Shur-Lock 6 hole semi trailer connector like the one already installed in the bed but these are very old and i'd rather save them for a period correct truck. These Berg Shur-Lock connectors seem to be pretty darn rare now days too, I can not find much of anything on a google search. Luckily I have two female connectors but no male connectors to match. I will be getting new Hopkins heavy duty 6 hole connectors for the bed and bumper. The Pollak plug I installed in the bumper is a bad plug but I used it so that I could get my holes drilled correctly. Ended up putting in larger holes that I wanted but oh well. The brake controller I installed in the cab is a Tekonsha Voyager from 2004 and while it is almost 10 years old I am still going to use it because I don't like the newer style ones and this one is still good. Heres some photos.

Well I did manage to get some new photos of the GMC hooked to a gooseneck trailer for the first time in about 20 years but more on that in just a minute. Most of my free time today was spent working on mowers. Yesterday one was dropped off for servicing, this morning I had to pick one up for servicing, and tonight my stepdad brought me two to service and fix the recoil on one. If these mowers keep flowing in like this I wont ever get my project truck funds back up but hey business is business and people gotta mow their grass.

Getting a lot of small engines in for servicing



But I did get some cool new photos of the GMC with its first gooseneck trailer in almost 20 years

[98Murray]

Because I had a little extra time today and wanted to try out my tripod stand for my camera I got some photos of the dump trailer

[Wrecked1982]

Yep its a 1980 King Goose 12 tonner. Use to be a grain trailer with metal sides but they're long gone now.
