What have you done to your square lately??

[Truck82]

I looked up my engine block 3 letter code. Turns out my 83 C10 has a 1975 350 rated at 165HP. It’s now power house. It’s definitely been rebuilt. I wonder if it has the original cam.

Found out my ‘82 c20 has a 1970 350. I love surprises!

A 70 could be higher compression.

I'll take this challenge, But It's a list of what I did since the middle of August. I dragged home an '83 GMC that had been in a shed perhaps since around 1988. Wisconsin Truck, so there are a few little holes but nothing major. 71,000 miles on the clock. I'm 65, retired just a few months earlier and this was a lot of work for one old guy ! While there is more to do, I love driving it. Wherever I go, someone comments or asks if it is for sale. Can't sell it... I'm over budget ! Image below is how she looks currently.

I have a visitor in for service! 350 with a quadrabog runs like **** over 8000 feet of altitude. Cannot pull the hills. (it doesn't fit in the shop)

Try rebuilding or adjusting it properly. No one has EVER made a carb better when it's tuned properly.

Recently I depressed the parking brake and the parking break light has stayed on on the dash. This is why I have avoided using the parking brake. In the past I have managed to get the light to finally go off but I cannot remember what I did. It seems like it is directly related to the parking brake pedal being so loose it pulls up just enough to make the ball sensor on the end of the line rest on the metal and send the light to the dash. I have looked in to a few things that may lead to this indicator staying on. The truck drives fine and brakes with no issues. To me it seems to brake with all four. I read about how the proportioning valve works but this doesn't seem to be what is sending the light on. Maybe someone with more insight on this could educate me as to how it actually could be within the proportioning valve. Again, the light on the dash only stays on after the parking break has been used and when released it seems to release all the way but the pedal drops back down just enough to set the light. I also have seen videos of people demonstrating going back and forth from auxiliary to on on the ignition column can clear it but on my 87 truck there is no auxiliary to turn the key backwards in to. Do I have a not original to the truck steering column possibly? Any insight would be greatly appreciated.

While pulling the brake release lever, pull up on the backside of the pedal with your foot, this should make it go back to full release position & make your light go off.

Finally got around to cleaning out my shop enough to get the truck pulled in. I bought a truxedo cover for it earlier this year and also new high strength tailgate mounts. I'm supposed to be heading out hunting this weekend and we are in the middle of an atmospheric river, so I wanted the bed cover on before going out. So, after over a year of driving around with the bed loosly held together, I finally got the back of the bed bolted together fully and re-welded at the rear posts. Then pounded out the parts of the tailgate brackets that had gotten bent and messed up over the last year of driving around like that and then installed the cover. Turned out fairly OK and will get pulled back apart after hunting is over to fully clean/seal/weld and reassemble the bed before I undercoat and then raptor liner the inside of the bed.

I didn't even have to rebuild it. The secondary air doors were stuck closed as the dampners were removed and not connected (front removed, rear connected to full vacuum. Disconnected the remaining rear ones, and doors now open on demand. A little rough on response, but the truck has its power back.

Finished removing the last of the aftermarket stereo equipment and restored the kick panels to something at least closer to stock.

When I got the Blazer it had what I’m sure is a nice high-end stereo system installed. There were 3 big, heavy speaker boxes in the back, speakers in the kick panels and a 1600 watt Kenwood amp mounted under the drivers seat fed by a power cable that looks like it could supply a small city. As a result the back seat was inaccessible and the kick panel speakers were always getting kicked. When I go after the dash pad I will install a new dash speaker and hook that to a simple AM/FM radio.

Finished installing fender badges and dash badge. Officially showing GMC rep now!

Also bonus pic of engine. Still struggling with AC freon not flowing through orifice tube properly and freezing up. May just give up and take it to a shop at some point. Will be the first time this truck sees a shop outside an alignment in over a decade.

How did you get the old fender badges off?

 

[Drauka99]

Got the rear glass installed and the drivers door handle and sport mirror installed. I’ve been chipping away at getting all the trim and everything back installed. Got the windshield in the other day. I went with a new one with the antenna in the glass.
