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.

Pulled the Quadrajet off of the 76, it's been in need of throttle shaft bushings and the well plugs have been leaking for some time now. 200k+ miles on it though, so hard to complain too much. Will be going through the ignition system and making new plug wires for it.

I am officially saying I am done painting (other than a few tiny touchups in seams where I couldn’t get paint to flow). This picture was Sunday after I shut down for the afternoon. I went back out this morning and taped it up again and scuffed up the green and then reshot the green. There were a few iffy spots on it and some debris that was driving me nuts. It’s good enough for a driver and that what I wanted. I’ll start getting all the trim and grill and such back in it now. I have new sport mirrors and door handles on other so I won’t be getting the doors done till those come in.

Love that sound! Still saving up for some long tubes though. I’ve got the glass packs dumped at the axle with no pipe after them but have heard they will sound better with a tail pipe. Any suggestions or leave them as they are?

I have long glass packs, and just dumped right before the axle as well (long bed) with long tube headers, and I love the sound. Not terribly loud, but you can still hear the 80's when you get on it. LOL.

So it’s November 11 in central VA and I’m going once again driving around in the topless blazer wearing nothing but jeans and a t-shirt.

The new ColdCase radiator and fan unit works great. I gave the old radiator (a Summit aluminum unit installed by PO in June 24) a good look and saw why it was leaking-cracked welds around the lower hose connection. Aluminum can be a b…ch to weld.

Note: Stock photo.lol

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.

What I did was discover a brake issue on the way in to work this morning . At work I discovered my aftermarket PV2 proportioning valve is leaking from the "nose" seal . (Left side if looking at it while mounted on the truck)

What I will be doing is replacing it with my old one that I had to drive home to pick up in the company shuttle...

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.
