r/squarebodies

1979 K10, 400 sbc, Intermittent no crank.

It has only happened twice but I hate the idea of being stranded. It normally cranks like a mad man. I first thought it's the solenoid/relay switch but I don't think I could hear any click so I am now wondering if it might be the ignition switch. This last time it failed I started it and it cranked well and ran fine for around 20 minutes. I shut it off for about an hour and then when I tried to restart it nothing! The on position of the switch seemed fine, the dash woke up and the fan came on. I moved it to the start position, the fan stopped and no crank, release the key and the fan came back on. This repeated for about ten attempts. The battery voltage was well over 12 but I don't remember the exact value. I got a helper to turn the key while I read a voltmeter and it cranked quickly and started perfectly first try. Battery is relatively young and good with clean connections.

What do you think should be my first steps?

Edit, I should have added that my helper could see no dimming of the headlights when I turned the key to the start position.

Thank you for reading.

1979 Chevy Silverado Scottsdale

Rust free, my new project. I want to put a small block 350 in it and an automatic transmission but I don’t know what year motor and transmission to get. Budget build, I’m new to this and I need help understanding.

Looking at my first square body, should I buy?

1974, engine rebuilt 5 months ago, transmission, transfer case. Runs and starts up, took it for a test drive and it died twice going in reverse, worried it might be a ground issue. Gauges don’t work either, offered him 6500 for it but he won’t go lower than 6900. Told him I’d have to think about it, hoping he’ll come back liking my offer. What do ya’ll think?

Rare CUCV sighting.

I saw this beauty at the boat ramp yesterday. Glad to see her still working. Looks like an old 1986 CUCV. A bunch of fire departments bought them from the government after they were decommissioned.

Grandpas 84 GMC Sierra Classic

I’m going to be trading my grandpa a new furnace & air conditioner for his 84 GMC Sierra Classic, it’s been sitting in the garage for 20 years, he said starts it once a week but is getting too old to mess with it. I’m going to be towing it to a shop once I’m done installing his equipment, what should I tell the mechanic what all needs to be done to a truck that’s been sitting for so long? It “runs and drives” but he doesn’t trust it making it home in one piece probably needs new tires and brakes inspected. If the truck truly runs & drives with just getting some maintenance done on it, how much do yall think it’s worth? I don’t plan on selling it but just curious. No rust, it’s lived in a garage its whole life.

Got her fixed up

Picked up this c10 a couple months back for $1000. Non running and full of trash, but rust free in all the right places. Finally got her going and fixed up enough to feel good about it.
