    1987 Burb TBI to carb swap

    I have actually been chasing vapor lock on my truck , when the outside temp hits 95+ degrees you can watch the fuel pressure drop to nothing on a hard acceleration or sometimes just pulling away from a light. Adding any resistance in the suction side of the fuel pump is not good. Might get...

    1987 Burb TBI to carb swap

    pulling through the in tank pump can lead to vapor lock issues. however the pump could be replaced with piece of hard line and a filter sock.

    Fuel line questions

    simple way to measure stuff like this is to use a open ended wrench , kind of like a go no go gauge. the 5/16 will not fit over the fuel line , the 3/8 fits and a 9/16 fits loose. there fore you have a 3/8. I use this on bolts all the time but works with hard lines too.

    Catalytic converters: does your square have them?

    When I was looking to buy a truck of my requirements was a truck that did not come with a cat or EGR from the factory. In 77 the heavy half tons did not have them.

    How long does your Q-jet hold fuel in the bowl?

    In the summer time in AZ the float bowl will go dry from simple evaporation , mine will go dry overnight and I have verified the well plugs do not leak. If your fuel pump is loosing its prime then the pump is bad. The float bowls on a Holley are HUGE compared to a Qjet probably about 10x...

    Turn signal power?

    you cant always look at a glass fuse a see its bad. When testing a fuse with a test light ,first attach test light to a good ground , next touch test light to both ends of the fuse. If test light lights on one end and not the other= bad fuse , if test light lights on both ends = good fuse...

    Turn signal power?

    The horn is a different circuit and the column just grounds it. Hazards and T/S are on different fuses. I would recommend starting the truck and then using a test light on both sides of each fuse.

    Temp Sending Unit

    Gauge parameters varied For Truck Years: 1967 - 1973 The Temp Gauge Needle Should Point to: Left Line (Cold) when sender resistance = 350 Ω Middle Line when sender resistance = 76 Ω Right Line (Hot) when sender resistance = 51 Ω For Truck Years: 1974 - 1978 The Temp Gauge...

    Overdrive Trans or Ring and Pinion swap?

    Gear vendors overdrive may not be the cheapest option, but you would keep the strength and towing capacity while lowering you highway cruise RPM.

    Emissions sticker

    We dont have to pass emissions where im at either. I do have a nearly complete set of emissions parts stored in boxes, if my truck ever had to pass. I fear someday the Feds / EPA could mandate nation wide testing and retro it back to 67.

    Emissions sticker

    I couldn't find one for my 77. I ended up doing lots of internet searches till I found a good pic of the correct label. Then I had this company make one for me https://www.vinslabels.com/order.html . 2 catches , they require a photo and only sell to body shops. So I opened Kingman...

    Factory Cruise Control and Dakota Digital with GPS

    I converted my truck to use the factory 1991 electronic speedo, when I set up the cruise control I initially hooked it up to the the 4000ppm output instead of the 2000ppm out put and it wouldn't engage below 50 mph.

    Factory Cruise Control and Dakota Digital with GPS

    I would think that's a possibility.

    Factory Cruise Control and Dakota Digital with GPS

    To the best of my knowledge for an 86. the speedo cable turns at a rate of 1000 RPM (revolutions Per Mile) and there are 2 tabs that the sensor sees meaning 2000 PPM signal.. The other problem you might have is analog vs digital. There is a good chance you will have to run the VSS to...

    86 c10 Driveline is too short

    You have 2 different things going on . First the difference between a th350 and a th350c is the C has a lock up torque converter. C has nothing to do with overall length. TH350th/350C transmissions came with 6"9"12" tail housing depending on application. my experience is trucks got the...

    More quadrajet help please! Won’t run

    A air fuel ratio gauge is probably the easiest way to take the guess work out of tuning, especially with modern fuels. In addition it will help you tune the APT power valve screw at cruise..

    What have you done to your square lately??

    tracked down a short to a bad torque converter solenoid, fortunately I had a spare in a junk transmission. Also removed the corvette servo , went back to the original to soften up the 1-2 shift. Didn't like it banging into 2nd.

    Bending Hood

    As others have said clean and lube the hinges, push back as its coming down will eliminate most bent hoods. I added home made stiffeners for added protection. (I believe the rivets will sheer off in a bad wreck)

    Can't figure out how to build new wood bed floor

    2. Do the wood planks UNDER or OVER the lip at the front of the bed? Over. 3. The angle bracket on the sides of the bed have those bolts in them. They don't want to come out, before I start torching or cutting, any tricks? They are welded in place 4. Can the angle bracket be removed all...

    What have you done to your square lately??

    had to replace the rear yoke. When I swapped rear end gears the drive line vibration got really bad, turned out the tits that center the rear ujoint were worn allowing it to run off center. Above 60 MPH it had a horrible drone.
