    Ball joint

    A few things to try. First, replace the grease fitting. It is probably clogged or rusted. When you have the grease fitting out, check the bottom of the fitting hole and make sure it is not plugged at the bottom with rust or crap. This will solve the problem 90% of the time. They are like $0.50...

    Replacing K20 fuel tank

    If you try to replace this valve, just learn from my mistakes; I decided to replace the Pollak valve when I had the tanks down and I was installing intank pumps. I purchased this valve new from Autozone, and it was junk. It was nonfunctional out of the box...

    Rear Brakes Locking Up

    @Goldie Driver; when you have eliminated all the possible, what remains no matter how improbable, must be the truth. So if you traced them from the PV back to the MC, then what you found has to be the truth. I can’t really tell from your pictures how they trace back, but those lines don’t look...

    Replacing K20 fuel tank

    The valve can be changed from the ground, it isn’t as bad as it looks. When you have the passenger side tank down it is even twice as easy to do. It is only two bolts. Cut the hoses to get it out and replace with new fuel line. It’s a 90 minute job, even with the passenger side tank still up...

    Heat and AC

    I would check the switch valve first. Get under the truck and have someone throw the switch and see if the valve is making noise. Two options; disconnect the wiring harness off the pollak valve and use a test light to map it out. If you have power on two separate wires (when switched)...

    Best rebuilt th 700R4?

    If you are in AZ, ship a core to @NicksTransmissions in Las Vegas. It is your safest bet. If you watched some of his videos rebuilding a new "HD 700R4" that melted down, you'll realize all you are paying for sometimes is stock parts and black paint when you buy them through the mail. Would...

    Dual tank install

    Hopefully your wiring is still in place. The switches are available on LMC. Just make sure you get the right year. If they left the wiring for the pollak valve you are in good shape. Put up two new tanks while you are there. It’s like an extra $100 each side. Also, Pro-tip; extend the fuel...

    dies at low idle speeds, when put into gear and when stopped.

    OP, Look for air leaks between the carburetor and intake manifold at the gasket. It’s usually an easy starting place and could explain symptoms of vacuum leaks or mixture problems. Idle RPMs should be around 900 (give or take 50 depending on your set up) I keep mine around 850. If idle rpms...

    1981-87 Chrome body side molding

    LMC makes precut kits too. My set is going on three years without issue, but full disclosure, mine stayes in the garage. Make sure you edge buy the sealant for the ends. Without it, water gets in and ruins the trim.

    8.1 vortec into 1979 k30

    I like your fab work on top of the cold case radiator to fill that gap, I have the same issue I am trying to solve. I bought the same one and, this is a rare case where I am really impressed with the fabrication quality of a product. Cold Case Radiators are expensive, but once the bill is paid...

    fuel line clamps

    Pumps for carbureted fuel systems are only 5psi-ish give or take (between 4-8lbs typcially). A good shoe strig will probably seal 5lbs of pressure. Spring clamps are pretty much industry standard for the the past 20 years +

    Rough country lift

    The heavy duty front end is enumerated on the build sheet (F60 Heavy Duty Front Spring). I imagine that it is basically a mid 80's version of a snow plow prep package or something which lines up with my trucks original build because it also came with UA1, Dual Batteries. We have several...

    Rough country lift

    The short bed K10 suspensions are unforgiving. The trucks are light, and have a short wheel base. They get the same spring treatment as the long-beds. Mine is a stock suspension with the industrial front end and it rides like tractor with a better radio. This is the main reason I don't want...

    '82 K10 Fuel Gauge Pegged

    The only thing that change was the circuit board, and everything worked before that. Easiest diag is to send it back and try another. Have LMC replace it or try another company. Don’t beat your head against the wall with anything else until you try this. I am going to do a post soon on the...

    AN fuel line kits

    The best way to cut the tubes is with a dye grinder. Before you cut anything, make sure you make a good tight (and thin) wrap with Electrical tape to prevent the braiding from unraveling (which it will unravel a little but don’t get intimidated). 6AN is basically the same as 3/8” hose. Braided...

    Custom Fuel Tank Location - Filler & Vent Hoses.

    Yep, make it. Or have it made. It doesn’t have to be a TIG job since it will be hidden. No need to make it super fancy. A good MIG guy will make it just as good. Have him make 10 and put 9 on eBay. You might be famous. Would love to see this set up when you are done. That tail light set up is...

    1973 ignition cylinder, back together issues

    I believe I read on here some place that if you follow an amazing link from this site, that GM Squarebody earns a small amount of money, so I try to post Amazon links if I can.

    1973 ignition cylinder, back together issues

    There should be a steel plate that goes over that spring that is the steering wheel lock when the ignition key is turned to the off position. That play is then held in place with a snap ring. You will need a steering wheel compression tool to get it back together. https://a.co/d/a2zFBci

    700R4 Transmission Questions/Issues

    I had one that acted the same way after a service. 2-3 clutch was smoked. Fine the day before, then ruined. People can give you some opinions, but unfortunately, there is no way to find the real problem without getting into it. And judging from how much clutch material is in there, there is no...

    700R4 Information Thread

    Thanks for these suggestions Nick. I have tried to adjust the TV cable to bring this up. Park/Neutral/Drive/3rd and Reverse pressures increase, but low and 2nd stay the same. This is allegedly a new valve body, so it should not be a worn bore, but anything is possible. I will follow up after...

    700R4 Information Thread

    Nick, I recently got the 700R4 from my 85 K10 rebuilt. Transmission is installed and before I moved it, I pressure tested the trans per your guide and dialed in the TV cable. Here are the results; 1. Park/Neutral/Drive/3rd - 85lbs @ 1,000 RPMs 2. Reverse- 140lbs @ 1,000 RPMS 3. 2nd and 1st...

    700R4 manual low and manual 2nd low pressure

    It is actually a good question, should have included that. I am using Dexteon VI. The tech said standard fluid is fine (not that he is necessarily correct). Heavier clutches were part of the build along with a new valve body and 2nd gear servo. I asked for an itemized parts list so I know what...
