Need help with my squarebody
I inherited this truck off my great grandfather and when I first got it didn’t run and then I got it running good, then I decided to tow it a couple months later to my place and I started it and sounded cammed and gave off a decent amount of white grey ish smoke colour on idle and black smoke when I gave it gas. I’ve changed spark plugs and wires, distributor rotor and cap, fuel filter, fuel pump, got carb rebuilt by a old school mechanic, siphoned old fuel out and put new fuel in with Sea foam, new heater block, did an oil change before the oil was black and smelt like fuel but flowed like normal oil and there wasn’t any shavings or anything. with the new oil in and runned a bit it smells like fuel but still is pretty clear but there’s a tiny bit of black and I’m 90% sure it isn’t head gasket or coolant in engine because I haven’t lost a lot of coolant and it doesn’t smell sweet. The carbourator choke doesn’t open and it’s a hot air choke and can’t seem to get it to open I think it’s something to do with my carburetor but if anyone has any advice on what I should do next would be greatly appreciated.
Found these bed rails on Facebook marketplace. What do you guys think before I make holes?
What long tubes don't hang below the frame rails?
I currently have stock exhaust manifolds in my '76 C10. It gets the job done in my.060 over 350 with mild cam, some head work on the iron heads, aces Killshot fusion, CVF Racing serpentine kit.
The truck is on bags and lays frame. I had some summit long tubes on my 327 before I bagged it. The collectors hung down below the frame. That's why i swapped to manifolds.
In the near future I plan to swap a SBC crate engine. I am leaning towards a 383 or 406. Either way the manifolds won't cut it anymore.
Who has long tubes that don't hang below the frame rails? Who is the manufacturer? Or do they all hang low and I will have to settle on mid length headers? Ground clearance is highly important here. Although I don't really drag bumper anymore.
Easy fix?
I’m on the fence about buying this(late 80s k5) The first two are the left side of the floor in the corner in front of the back seat, third picture is the right corner in front of the back seat, the last one is at the end of the bed, so would this be an easy fix cost wise or an expensive hassle? The rest of the body is in pretty good shape and the frame is a little rusty but seems decent enough, I was going to offer around 10. Any advice or opinions would be greatly appreciated.
‘83 K10
A 35mm photo of my 1983 K10 that I recently took in front of an abandoned movie theater in my hometown. The truck’s springs are shot, so it’s getting a slight lift and new springs soon. Hopefully, some raised white letter 33s, too. I’m keeping the original wheels.
Square body Overland build
Throwing the idea around of selling the 2wd shortbox square body i built from the ground up in 2020, to fund a long box 4x4 mild overland/camping rig. my question is: would you buy a mint condition original numbers matching 2 owner truck (nothing special or rare about it) or start with something that’s rusted and needs paint and body plus the build itself?
1976 C20 body on a 2000 Tahoe Z71 4x4 chassis: swap at the firewall or strip to the frame?
Hey guys!
I'm picking up a 1976 C20 this week and plan to make it my winter build, starting after Dinos Git Down in November. The goal is to put the C20 body on my 2000 Chevy Tahoe Z71 4x4 (4" lift, 350, auto). I want a 4x4 big brother to the orange and white '73 2WD long bed I already have.
I've seen a few YouTube builds that put a C10 on a 2003+ Tahoe for the LS and modern features. I get the appeal, but I already own the 2000 and want to use it.
Questions:
Firewall vs. bare frame: Should I cut everything off the Tahoe but keep its firewall, then cut the firewall out of the C20 and graft the cab to it? Or strip the Tahoe to the bare frame and build up from there?
4x4 shifter: The Tahoe's 4x4 is a push-button switch on the dash. I have a 1992 with a floor-shift transfer case. Is it worth swapping to the floor shifter for a cleaner square body interior, or should I keep the electronic setup?
Bed: The C20 is a long bed. I'm planning to skip the stock bed, and I'm weighing three options: shorten the long bed, buy a short bed, or build a flatbed. Which way would you go?
Other details:
The engine and transmission are healthy, so I'm keeping them stock for now.
I have three OBS Chevys, so I have plenty of parts. A lot of the Tahoe's parts will go into Big Red, my '98 C3500 crew cab.
I buy and sell OBS trucks all the time, but this one is going to be my main squeeze.
Any advice from people who've done a square body on a GMT400 chassis is appreciated. Pics are of my tahoe donor the c20 and the third one is just a ai rendition.
Any thoughts or comments, please let me know what you think.
1985 K20
This is my first square body, and I’m getting ready to pull the 350 that’s in it and swap it for another that’s a little more spry. This is also my first engine swap of any sort, though I have done clutches, water pumps, injectors, and plenty of ride control work on my own before. This will definitely have a learning curve that I am ready for, with a lot of “learn as you go”. Do any of you guys who’ve done this a hundred times have any advice, or hidden hurdles to look out for that I might not have a clue to as a first timer? I’ve watched hundreds of hours of videos, and I know my way around an old Chevy pretty damn well. I’m just finally taking the dive to do something that’s always been a dream of mine, but seemed so overwhelming to start! Thanks in advance for any tricks of the trade, or tribal knowledge . Wish me luck!

Anybody have any good recommendations for tall n skinnies? Recently picked up this C&C k30, and am thinking on keeping the narrow dually rear. Would like to run some 33s, but cant go much wider than 9.5s. Was looking at the samson trakers, spendy but theyd be boss on the ol rig, cant find much for reviews on em though. And for any wondering, the tires on it are not great. Someone did alot of work on this one then just parked it. All new hoses, accessories, some top end engine work, new tires. Sat so long the tires have flat spots and are bubbling. Still got the hairs on em too, crazy
Household 10gauge wire for starter solenoid on a 1975 Chevy K10, should I replace it?
I replaced the wire running down to a small terminal on the starter of my 1975 Chevy K10 with regular household 10 gauge copper wire. I believe it’s stranded, but I need to double check. I don’t know the insulation rating.
It’s inside a heat resistant sleeve and isn’t touching the engine block. The truck has been starting totally fine so far, it’s been about a month and a half now since I replaced it and I daily drive this truck.
Is this acceptable long term if properly routed and secured, or should I replace it with automotive wire?
I take this truck into remote woods and want to avoid getting stranded. My mechanic has been unreliable so I’m trying to figure out whether this needs immediate attention or is something I can replace myself when convenient. Looking for input from mechanics or anyone familiar with these older GM trucks. Thanks!
1986 4.3 k15 to 350 engine mount questions
Hey all hoping to pick your brains on what I can do about my situation.
My K15 originally had a 4.3 v6 with a SM465 and I am trying to swap on a 350 v8 from an automatic 2wd truck. I have most things figured out until I was looking at my existing mounts and the ones on the two wheel drive were so different.
I know these frames were built to take any combination of engine but I was wondering what I would have to do to my v6 mounts to get the 350 to switch.
Can I just move my mounts forward one hole?
Should I buy a new set of mounts and if so which’s ones as everywhere I look it’s either for an LS swap or LMC truck only sells the 2wd frame mounts which won’t work for my 4wd frame.
Any help is appreciated and assume I don’t know very much in aftermarket options. I was hoping it would just fit in but in my infinite wisdom I forgot the V6 sits farther back.
