    Hi from IL

    Since it is a fairly small amount, it is possible the front motor mount brackets were moved. They are slotted and have fore/aft adjustment.

    Installing a New Exhaust System Including Headers

    I used the ceramic Headman long tube headers and they fit very well. I also used the Walker exhaust kit and it all fit nicely. I just replaced the connectors with some better quality ones. I had to use the Headman headers because they were the only ones with the AIR tubes and were CARB...

    Finding smog pump 1985 Chevy K20

    For my 1976 K20, I had RockAuto rebuild mine. The advantage of rebuilding yours is you know it fits. I think I also got the diverter valve from Rock Auto. There is also a rebuilder on eBay. Seller's name is "BZ Rebuilders".

    clutch pedal assembly- 87 hydro

    I've got one I'd like to get rid of. Came out of a '76 K20 with hydro-boost. It wasn't original, had been scabbed-in by a past owner. Missing part of the clutch pedal that bolts on (see pic) The mounting flange at the firewall got tweaked a bit. Needs some straightening and a weld...

    Wanted: Stock 4X4 Steering Arm

    Anyone have, or know where I can get, a standard steering arm (not raised) for 4x4 (Dana 60 front axle). I only have a 2" lift, but my truck came with a 4" raised steering arm, which messes up the bumpsteer.

    np203 shifter

    Step 7: Final Assembly Place the other housing over the assembly and install the hardware For the large bolt through the assembly, be sure to use a lock nut, not just a washer. You don't want to jam this bolt down and clamp the assembly tight. You want everything to rotate/move freely...

    np203 shifter

    Step 4: Install the plate with the jog facing "down", as oriented in this picture. The next plate will have the jog facing "up". Note: Have the hole in the plate line up with the hole in the housing. This will help assembly in later steps. Step 5: Install the 2nd plate as shown. Again...

    np203 shifter

    Update on my 203 Shifter Rebuild: I had the parts coated with black Cerakote last week. They turned out great. It think there were 10 parts and it came out to $200. $20/part wasn't bad. They coating is very hard and has a teflon-like feel. As I put it back together, I used this for...

    Rust removal

    I must be the last person who has discovered this, but just in case there is one last soul out there that hasn't, I wanted to pass this along. I had some parts that I was going to media blast, but a few items are assemblies that can't easily be taken apart, like hood latches, parking brake...

    np203 shifter

    I'm in the process of rebuilding mine. There is a good YouTube video out there. I ended up buying a spare shifter as a reference, just in case. I may make a video or a detailed description of my rebuild. I've studied the mechanism, and it is clever, but faulty in its crudeness. It is...

    Passing CA Smog help - High HCs

    The fact that you had to open up the carb and make repairs on a "fresh" carb concerns me. I'd definitely reach out to National to get their 2cents. If those basic items were wrong, then I'd question the whole thing. If you wanted to check, you could verify the idle mixture screws. You could...

    Passing CA Smog help - High HCs

    Man. Sorry to hear that. I was hoping yours performed like mine. As DoubleDingo mentioned, it would be great to get some more specs on what is going on. I'll relist a few: * Vacuum reading: Value and is it stable or bouncing around * Timing: Value (unplugged from port vacuum) * Spark Plug...

    Passing CA Smog help - High HCs

    Did you get it to pass smog with the new Qjet carb? I got the same one you did from National Carburetor. The truck actually starts and idles better than with the Edelbrock 1400 I originally had on it, and I haven't made any adjustments yet. We'll see once I'm able to drive it, but so far, I'm...

    Need: 1976 Chevy K20 Emission Label (or pic of yours)

    Here is a diagram from the Factory Shop Manual that I'm following. The diverter valve is connected to a port on the Qjet just behind the choke pull-off valve, and tees into the bottom port on the thermal (spark control) switch on the water neck. Note, there is also a port that goes to the...

    Need: 1976 Chevy K20 Emission Label (or pic of yours)

    I'm still waiting to get the pictures. I'll ping them again. If I am successful in getting the pictures, I'm hoping to work with the current label supplier to get one made that matches the picture I provide to them. This will likely be a lengthy process, but at least an option to finally get...

    Need: 1976 Chevy K20 Emission Label (or pic of yours)

    I haven't. I've looked through the forum as well and haven't found one with my combination. I may have found a truck that has this combination and I'm going to see if the owner could get me some pictures of the labels. If successful, I'll pass them along.

    Engine Stalling - Bad EVAP/Charcoal Canister?

    Good catch on the power piston. Glad to hear it is running better. I'd highly recommend gathering as many parameters on the truck as possible (vacuum, timing, fuel pressure, AFR, etc..), especially when it is running good. That way, if it starts to run poorly, you have a baseline and can tell...

    Need: 1976 Chevy K20 Emission Label (or pic of yours)

    Thanks for pointing me to that thread. Definitely worthwhile to compile as a library for other members. If I'm able to get a pic of the one I need, I'll be sure to add it.

    Engine Stalling - Bad EVAP/Charcoal Canister?

    Thanks, Ricko1966. I wasn't sure if the evap canister allowed flow back into the tank. I agree it is a good thing.

    Need: 1976 Chevy K20 Emission Label (or pic of yours)

    I need an emissions label for a 1976 Chevy K20 with; 400 cu. in. engine California HD Emissions (has AIR, EVAP, PCV. Does not have EGR or CATS) I've searched everywhere, including Classic Industries and LMC, and haven't found the label. If someone has one on their truck, please provide a...

    Engine Stalling - Bad EVAP/Charcoal Canister?

    @legozombie Have you been able to test out Ricko1966's tests? I'm currently in the process of installing the fuel system on my 1976 K20 and am curious what you find. I spent most of last week trying to understand how the evap system works. I fully agree it sounds like a vent problem. What...

    Passing CA Smog help - High HCs

    For those switching from Edelbrock to Qjet, here is the parts list I've come up with (so far); Choke: Since the Qjet 4MV carb has a divorced choke (and I don't have the choke) I am going to try one of these out; https://www.carburetor-parts.com/choke-kit-cu1445 Hard Fuel line from pump to...

    Passing CA Smog help - High HCs

    Yes, that is the kit. Maybe they figured out an offset to apply given the O2 being added from the air pump. I found a couple of threads where someone had trouble with it, so I hesitated to go down that path. Given the O2/fuel ratio is fundamental to how the fuel injection works, I'm just not...
