    Milky oil after 1984 K10 305 top end rebuild.

    Yes, it’s factory bore plus 0.0X0.

    Do I have a limited slip differential?

    I guess we both learned something. I would have assumed it was open since the spring’s not right there like in the Corp 10 rear.

    Steering Column advice.

    Everything you could need to rebuild, especially if it’s a tilt column, should be readily available. It’d be more sensible to tear it down in the truck, tighten the slop and loctite the four bolts, and assemble your way back up while replacing what you need on the way back up. A new lock...

    Underhood lighting

    Yeah, the one Jerry’s telling you about is in the W Bodies and a rash of others. It’s a neat idea. What you want is the single wire mercury switch light that kicks on when the hood’s opened a certain amount. Any old B/G Body should have that, and I would check the Fs and Corvettes, too. I think...

    Hello from TN, looking for old 77'

    I wish I had a better memory for small details like this. I saw a truck that looked very similar in Nashville almost five years ago, but it was white. It was owned by a scraggly guy who was dirty and looked like he smoked a lot of cigarettes, I told him it was a nice truck, and he said thanks...

    Oh, I thought you were commuting from New Iberia to one of the ports.

    Is this in Laplace or New Orleans? Or neither?

    A/C Box- WI (FOUND)

    The only reason I ask is because the weather’s been real nasty here, and the cab in question would have me getting mucky to pull the evaporator case. I’ll snap some pictures for you when I can, and I’m sure HRPC will check his stash out, as well. If he beats me to it, I won’t mind, and I know he...

    Best Front-end Rebuild Kits

    Bear in mind that there are two AC Delco lines, a cheaper one and a more expensive one. People have had problems with the cheaper line of ball joints and control arm bushings, almost certainly made in Asia, but the more expensive stuff is consistently well-received. There have been a couple of...

    steering wheel removal

    You compress the lock plate with the tool, that gives you room to undo the lock ring, and this lets you remove the plate, the canceling cam, etc. https://www.gmsquarebody.com/threads/how-to-fix-loose-gm-steering-column.3085/

    Link Belt vs. (Double) Roller Timing Chains

    Hmm, I checked to make sure the bolts didn’t back out, and I did plug the smog holes, but I used the correct inverted flare plugs. I’ll be sure to check for cracks and go back and make sure I didn’t miss anything.

    Catalytic converters: does your square have them?

    You might be onto something. 35 year old single exhaust looks brand new, the dirt notwithstanding, on the car, but the true duals on the truck not so much. I would like to see duals that old on a vehicle that’s driven at least three days a week. Also, I really don’t think these little cars and...

    I might be able to help. What’s your timetable looking like?

    Link Belt vs. (Double) Roller Timing Chains

    I got a video of the noise some days ago. I haven’t done anything with it yet, but I’ve only been using it for errands and small stuff. Just to reiterate, the noise is gone when it’s warmed up, and it only happens if it’s sat for a few days or if there was a temperature drop. If the temperature...

    Mechanical fuel pump tank return bypass?

    I couldn't agree more. My car was made literally weeks before they started putting return lines on them, and it will not fail to vapor lock after a hot soak with ambient temps of >80*F. If I knew what I know now back then, I would have gone with the three line sender, ran a braided line, and...

    Catalytic converters: does your square have them?

    No. I don’t hate them or anything, but sooner or later they start to come apart and rattle, and there are enough things to rattle as it is. My little car has been rattling, but in that case I’ll probably try to gut the cat so it still looks right if I ever drive it to a place like the Banana...

    Removing Smog on a 81 305

    Smog and air injection are different names for the same thing. You’re keeping the TCC lockup switch. I’d probably say to hell with the distributor delay since the EFE TVS is gone. Wait, why are you getting rid of the A/C? That compressor’s seals are 100% likely to be shot from sitting so long...

    Removing Smog on a 81 305

    The air injection system, EFE, and the TVS that controls it would have to go for me. The TCC lockup switch would have to stay. I’d keep the PCV and canister because they perform jobs that are worthwhile IMO. The EGR would be up to you, and I suppose the EGR TVS would have to stay anyway to keep...

    Hey all. Hello from Oregon.

    $450 is an incredible score. It looks like the rust isn’t too bad either. It must have been a shell, or you just lucked out on a seller that wanted it out of their sight yesterday. Welcome!
