    New For Me 1985 Silverado 20 6.2 Diesel

    The problem was that you ran out of fuel. It takes a lot of cranking to get all the air out of the lines when you do that(if it ever will). You usually have to crack the fuel lines at the injector pump or the injectors themselves until you start getting diesel to pump out while cranking. Then...

    90 vs 140 gear oil?

    Other than there being absolutely NO REASON to do so? '85 C10 should be a 10 bolt rear. It's basically identical to the 10 bolt used all the way up into the 2010's. My 2011 K1500 Suburban calls for 75-90 synthetic and I usually use this...

    4L80e 1987 C 10 ls swap not shifting

    I bet you have the connector plugged in upside down. It's a common problem on swaps, especially with standalone harnesses. Make sure that the person that built the harness put the pins in the right spots and also that you are plugging it into the transmission in the correct orientation. Make...

    Lotsa nice squares on CL out here right now!

    Damn... I'm really tempted to go get it. I probably don't even need a trailer, just flat tow it down to salem behind the K25 with a Harbor Fright tow bar.

    No spark

    If it is backfiring out of the carb, you are 180 out. It was trying to fire before and not backfiring, so you just needed to turn it a bit, then try to crank it. You don't need someone else there, just turn then crank, turn then crank.

    No spark

    loosen the hold down bolt so that the distributor will turn with force, but not on it's own. Crank the engine while turning the distributor slightly clockwise or counterclockwise until it fires off. Once it has fired off, set the timing with a timing light.

    Turn signal issues

    Start simple and don't get yourself going down a rabbit hole. Check all bulbs first. Then check all grounds by actually verifying continuity to ground from the terminal itself. Every single square I have ever owned has had issues with the ground wire connection at the bulb socket itself. It will...

    No spark

    My other thought(if all the wiring is correct), is that a pop but no start is exactly what you would get if you have the distributor installed 180 out. If you find that you have all the wiring correct and 12v at the coil+ with the ignition on, then you should turn the engine over until you have...

    No spark

    Can't really tell anything from your pics. What happened to the factory wire harness IGN+ wire? A '77 model year would have been factory HEI, so you should have a solid 12v source wire right there to tie into the coil. According to the summit instructions you wire the distributor like this: My...

    81 350 SBC is farked, about to replace with 350 SBC bought locally

    1975 Model year and older does not need a smog inspection in California. They can still get hit with citations for things if you are pulled over by a cop and that can lead to other issues, but 1973 and older doesn't even have any emissions requirements under the clean air act... so they would...

    Help!!! Flywheel bolts keep coming loose

    I have NEVER seen a properly torqued flywheel bolt come loose. Either that mechanic hasn't had his torque wrench calibrated in too long, or he didn't do something right. Loctite needs clean threads to really work properly. What torque did the mechanic say he used? Were they just stock flywheel...

    D44 longer Wheel Stud P/N needed

    I have run two separate sets of aluminum wheels on my K25. Both sets have plenty of stud engagement.

    D44 longer Wheel Stud P/N needed

    For steel, you need at least 1x the nominal thread diameter for maximum strength. 1-1/2x nominal thread diameter is even better. So for an 8-lug that would be 9/16-7/8" of thread engagement in the nut. Since the thread pitch is 9/16-18, you have 18 threads in one inch of fastener. That means...

    Smoked something

    Yep, two fusible links at the starter. There is also a fusible link that goes from that stud down towards the alternator. You probably smoked the fusible link from the starter to the fuse box for batt power(one is batt power and the other is ignition). You should be able to tell which one it is...

    GM 4200 I6 swap?

    Here is his build thread for the trailblazer: https://www.gmsquarebody.com/threads/03-trailblazer-build.41831/

    GM 4200 I6 swap?

    Your best best is probably to get an entire vehicle if you can. I think they just ran 4l60's behind them in the trailblazer... so nothing special there.

    GM 4200 I6 swap?

    Its @Vbb199 . He bought a trailblazer and I think he was going either the turbo or supercharger route. They are a pretty darn stout option, but not any cheaper than an LS in my area.

    What have you done to your square lately??

    I see you had to beat on your header for the #3 plug wire to clear. I was just doing the same thing on the ones I'm putting on my 2011. I would recommend swapping the MLS gaskets for Remflex ones. They'll never leak again.

    3 inch rake after tuff country 4 inch lift.

    Mine was a heavy GVW 3/4 ton with the F44 heavy duty front suspension and had all the original front and rear springs on it before I redid everything. Absolutely did not look like that. Mine looked just like that after putting 6" of lift in the rear and 4" of lift in the front. I think part of...

    Lift kit

    I also have the Tuff Country EZ-ride HD fronts and have modified the rear to run 63" GMT-400 K2500 rear springs and a 2.5" shackle flip. I have the ORD sway bar disconnect and just leave it disconnected unless I am towing or hauling a heavy load in the bed. Rides really good for a 3/4 ton, but...

    3 inch rake after tuff country 4 inch lift.

    No, not at all. That is WAY more rake than the stock 3/4 ton. Mine sat that way when I had 6" of lift in the rear and 4" in the front. It still has a slight rake with the lift being mostly leveled out, but nothing like that.

    3 inch rake after tuff country 4 inch lift.

    I would say that the fact you measured height before and after, and have a 6" lift in the rear should answer your question. You obviously got the wrong rear springs. My truck looked just like this when I put 63" rear springs on my truck in combination with a 4" shackle flip. I had read that...

    TH400 Information Thread

    Like Nick said, just pull the single bolt at the top of your picture and take the whole housing and gear out. It could be white and just discolored from the heat and grease exposure.

    Dieseling sometimes when hot

    He says its a new motor(I'm assuming a crate motor) and is running a sniper EFI. I'd be shocked to see someone put a sniper EFI on and then keep the stock SMOG equipment, BWTHDIK :shrug: Also.. we need pics in this thread before Rusty comes up in here and throws a fit.
